It appears that I have fallen in love with the mandolin. This was no overnight love affair, however. It kind of sneaked up on me.

As a longtime fan of the music of Antonio Vivaldi, I had heard my share of mandolins and associated the instrument with music from the past.

That all began to change when I attended a performance of Prairie Home Companion and heard the amazing Peter Ostroushko play. Nevertheless, I wasn’t ready to commit.

Then it happened. Several weeks ago, while listening to the weekly broadcast of PHC, Ostroushko performed the most glorious piece, something he’d written to celebrate a friend’s wedding. I didn’t remember the name of it, but when I saw he had a new CD, I decided to take a chance.

Sure enough, The A and A Waltz was included. It’s been the soundtrack in my car ever since.

I’ve been thinking about this slow love affair quite a bit because I suspect when folks hear about passion, they have a vision of being gob-smacked by something that grabs them by the shoulders and won’t put them down. Love at first sight, perhaps.

I don’t think it works that way. In fact, other than the births of my daughter and my grandchildren, I can’t recall any other times when passion was present from the first moment.

More often, it creeps up, like the mandolin, but it doesn’t come at all unless we expose ourselves to new experiences and possibilities. Passion isn’t passive; we have to get involved.

One way of doing that, of course, is to pay attention to the passions of others. People we love dearly and admire genuinely may very well have passions that leave us cold.

On the other hand, passionate people may get our attention simply because of their contagious enthusiasm. I’m not particularly interested in cars, but listening to Car Talk is a frequent pleasure on my weekends at home.

Opening ourselves to things that delight others may deliver lovely surprises we hadn’t anticipated. At the very least, we’ll benefit from the power of enthusiasm that raises our own positive attitude.

At the same time, we need to notice when a passion has passed its sell-by date. It’s extremely easy to spend time doing things out of habit because we failed to notice that passion has fled.

Sometimes when you partake in a long-time activity and find it no longer amuses or informs or entertains, you’ll begin to feel a bit of disappointment, as if you’d been jilted.

Some passions simply have a longer run than others. Just as closets need to be weeded from time to time, so do the activities that are worth our time and attention.

Thinking about collectors and collecting has had me contemplating the role of passion in a slightly different way. How do collectors decide what to gather? What’s the difference between those who build thoughtful and valuable collections and those who are simply packrats?

As I was musing about all this, I stumbled upon a delightful book called Merry Hall by Beverley Nichols, a British journalist and fanatic gardener.

The book  begins with a bit of a confession: “Some fall in love with women; some fall in love with art; some fall in love with death. I fall in love with gardens, which is much the same as falling in love with all three at once.”

Nichols goes on to tell his story of finding a wreck of a place in rural England that required years of diligent labor to transform it into the garden of his dreams. Thus began a perpetual hunt for interesting specimens to add to his collection.

It’s obvious that his passion for plants continued to increase even as the challenges involved expanded as well.

But, of course, passion is like that. It often has us doing things we never imagined we could do—or would do.

Whether that passion is for music, art, cars, food, gardens, social justice or any one of a thousand other things, ultimately passion invites us to become more, to do more, to be more. Eventually those enthusiasms infiltrate other areas of our lives.

“You have to participate relentlessly in the manifestation of your own blessings,” Elizabeth Gilbert reminds us.

Passion is a pointer to where those blessing can be found.

When the mandolin plays or the antique doll at the flea market catches your eye, pay closer attention and see where it leads. Give it time and see if it grows into something spectacular.

And if that doesn’t happen, keep looking. Just don’t insist on love at first sight.

Setting your life up to be lived as an on-going treasure hunt, can only happen if you’ve  identified things that enrich your life. Not all of those things are things, of course.

Here are some collectibles that enhance the entrepreneurial life.

° Testimonials. Happy clients and customers who take time to let you know that they appreciate your efforts do more than simply lift your spirits: they can also help you attract more happy clients and customers. Develop a system for saving the e-mails, thank yous and verbal words of praise.

° Experiences. Different experiences are good for your curiosity, your personal growth and, often, the basis of  your best stories. Why, then, do so many people fail to put themselves in new situations?  Habit, routine and self-doubt are some of the culprits here.

While all new experiences aren’t necessarily planned in advance, it’s a good idea to regularly put some on your calendar. Without them, you won’t have many good stories to tell your grandchildren.

° Joyfully Jobless friends. It was Napoleon Hill who first brought attention to the notion of a Master Mind Group. That’s still a fine idea, but you also need informal relationships with others who are self-employed.

Start following entrepreneurs on Twitter. Organize a local Meetup group. Find out about organizations and informal gatherings of self-employed folks in your area. Go to workshops and conferences aimed at the self-employed.

Follow up on recommendations of friends who say, “Oh, you should meet So-and-So. You have a lot in common.” Before you know it, you’ll have a tribe.

° Stories. More and more marketing gurus are  singing the praises of storytelling. Not only is this an overlooked marketing tool, many people overlook their own best stories.

Keeping a simple journal or file of stories you encounter—both in person or as a reader—is a good idea. When it comes time to  write a speech or spiff up your Web site or produce a mailing, you’ll have a pool of material to draw from.

Then there’s this from Michael E. Gerber: “I dare say, all successful entrepreneurs have loved the story of their business. Because that’s what true entrepreneurs do: They tell stories that come to life in the form of their business.”

° Portfolio of profit centers. There’s a line in the movie About a Boy that I love: “Two’s not enough. You’ve got to have backup.” They’re talking about relationships in the film, but it is equally true for profit centers.

As I’ve frequently mentioned, all enterprises go through cycles, but not all cycles are synchronized. If you have variety in your offerings, you can adjust, revamp, shift gears as necessary.

However, the flukes of the marketplace are only part of the reason for building a portfolio. You need outlets for all of your passions. An evolving portfolio is how you create the pieces of our own particular puzzle.

° Resources. The abundance of information available to us is both dazzling and daunting. Knowing that useful resources exist  can do a great deal to dispel fear and doubt, but only if you take advantage of the  best resources you can find.

Go beyond a Google search and find resources in your community, at the library, and, perhaps, your local visitor’s center. Does your local newspaper do stories about small businesses in the area? Are there local radio talk shows that might enjoy having you as a guest?  What about adult ed programs that can sharpen your skills?

° Expertise. Almost from the beginning of my entrepreneurial journey, I recognized that being regarded as an expert would be useful. Of course, if you’re passionate about something, growing into expertise is almost inevitable.

Using that expertise to expand your visibility, help others, make new discoveries, and create additional profit centers requires understanding the expert’s role and a willingness to value what you already have accomplished.

As I point out in my Establish Yourself as an Expert seminars, this isn’t something you do by the first Tuesday of next month. It’s an on-going, evolutionary process—one that keeps you stretching, exploring and growing. Doing so can also open doors of opportunity in delightfully surprising ways.
