What Drives You?

I need some help and advice, friends.  I'm pondering a question or two these days.  I want to know what drives you?  Or to put it another way, how do you know what your passion is?

And has your passion changed?  What if you strived for something for years, and then found yourself wondering if that's really what you're supposed to do?

I guess I'm directing this more to those of you in the arts: writing, music, dancing, acting, etc.  But it could be applicable to any vocation.

It's always challenging to go for your dreams.  It's a lot of hard work.  But when do you know when it's time to try something else?  Are you afraid of giving up too soon?  Or do you know when to face the realization that maybe you're supposed to be doing something else with your life?

For example, if you're an actor  -- you have a passion for acting.  But how long do you go along doing Shakespeare before you discover that you're a better comedic actor?  Or that you might be a better director or writer than actor?

I know we should pray about it.  I know we will just have a gut feeling.  But sometimes that gut feeling isn't as specific as we'd like.  Or God hasn't provided that neon billboard that says "Go this direction" instead.

So, I'm full of questions today. How do you know if you've found your passion?  What drives you to work so hard?  Even on the tough days or the discouraging days, are you anxious to get back to work to follow your dreams?  How do you know?

Questions, questions, questions!  Is this what happens after you turn 50 years old?

I'd love to hear your thoughts, advice or comments.
