Fear and the "can-nots"

A friend of mine recently started a blog and in his first post he discussed the fear he experienced which was preventing him from creating said blog. He challenged his readers to think about their own fears, and to consider what fear was keeping them from accomplishing. My thoughts came to me quickly, as there is something I've always wanted to do, but fear has truly kept me from doing it. I'd love to start my own business someday. There is a certain attractiveness in being my own boss and providing a service to customers as I have designed it. My dilemma lies in this: I'm wishy-washy. I change my mind often... Particularly over the last four years. Since September of 2010, I've changed jobs three times. They've all been promotions and better pay, but after my first experience of change (which was more necessity than choice), I've simply gotten bored and sought a different path. Another part of my dilemma lies in the instability and lack of security I anticipate when I truly start to pay my own salary (and maybe someone else's). I must admit, it's nice knowing Michael Dell cuts me a check when I've earned it. He's got clout. I've got... fear. Of course, his is a very encouraging and inspiring story. He started Dell as a college dropout with a $1,000 loan and turned it into a multi-billion dollar empire. After all, Great things start from small beginnings.
