You`re bringing up another (perhaps most important) part of this whole idea of exercises to find a passion. The topic is hopefully designed to help with practical ideas and examples of how people go about developing a life plan, finding a passion, and choosing a long-term entrepreneurial business idea.
Consider that you had this Most Excellent experience with making film. It sounds as if it is or could be one of your deep passions. You enjoyed it tremendously, discovered aspects of yourself and talents you hadn`t realized, and you were engrossed in the whole thing.
But you`ve also said---and it sounds as if it`s almost wistful---that you couldn`t pursue the field, didn`t believe you could make money, and implied that it isn`t a realistic goal. And believe me, I can understand your thinking. To compare the need to survive and earn a living with the totally unpredictable business of film isn`t even a valid comparison.
So what does a person do? Here they have what seems like a passion, but they can`t see any way to go after that passioin and still support themselves. Maybe if they`d started at 21, they wouldn`t mind sleeping in their car, but at 40 it`s not possible any more.
At 40 or later they realize they`re backed into a corner, can`t feel anything about working for The Man, and want to start a business. They look for a passion, can`t seem to find one, but just bypass that old passion they had long ago. It was unrealistic, after all, back then, so it probably is unrealistic today.
The thing is that at 40-something we have a whole lot more experience, wisdom, and even assets (hopefully) than we had at 20-something. We know more about life, and how to keep afloat in a money-based economy. We don`t see things as "all or nothing," and we can work through modifications of an idea.
For example, instead of chucking it all, moving to the west coast and jumping headlong into the movie industry, aren`t there any other possible ways to ease into that business? Couldn`t you start a video/film business with a specialization in some sort of niche? What about opening a sound stage where younger, budding film enthusiasts could develop their projects, or film students could work indoors with lighting?
The point is that a "field" of passionate interest ALWAYS is going to have primary, secondary, and other attributes and aspects. To say you have an interest in film doesn`t mean that the ONLY way to pursue that passion is to produce and direct the next blockbuster movie. Right?
What`s critical is to even know in what area you have this passion. When you have that global, overall area, then you can use logic and analysis to think up ways to come at it from different directions. You can start very small and work up, or you can start in the middle and move around.
I think what prevents people from seeing their passion is they think a passioin can only be valid if it will produce total financial success with 3 (or fewer) years. But a passion is a lifetime process. It`s something you have your entire life to move around in.
In many ways it goes back to the old success stories of long ago, where someone started by selling newspapers for a nickel, worked their way into the printing business, and eventually bought the entire newspaper. It`s the foundation of the American Dream, where you start with a pushcart and end up owning Wal-Mart.
Finding one`s passion is NOT the same thing as developing a busienss plan, starting a business, or coming up with a business idea! The passion only shows you the overall direction you`d like to go. It doesn`t plan the trip for you. See?
