Those are exactly my fathers words. I have definitely thought about this option, my fear is that I will get to 35 without having done anything that I care about in life.
Well, I was being about 50% sarcastic there. Personally I've been forced into entrepreneurship, somewhere around 37, because I realized my career wasn't going to go anywhere (in terms of either doing work I could be proud of or making $) unless I made some move.
At the age of 25, I just didn't have that sense of urgency.
