I've always wanted to be self employed. Seven years ago next month I hung out my shingle. I long ago crossed the line from fearing the phone wouldn't ring to catching myself wishing it would shut up.
As the business grows I surrender more responsibility. I hope to reach the point where I can watch the business and spend 3-4 months per year traveling.
I really enjoy having full decision making. I can't imagine retiring.
What business are you in?
