Great tech entrepreneurs who saw success in their mid 30s?
waivej: My entrepreneur energy has definitely changed (also in mid 30s).  Ten years ago it was all about the "great idea" and working really hard.  Now it's about strategy and observing the way the world works and choosing where/when to work hard.  I keep feeling like I should be able to "see" the big picture better.I think Ben Franklin said it well: "At twenty years of age, the will reigns; at thirty, the wit; and at forty, the judgement."It makes me think of a friend that's been an entrepreneur for 40 years.  He carefully planned a new business where he could work 15 hours per week and make very good money.  It's like he doesn't waste time doing anything unnecessary.
