What keeps you away from starting startups? 
Edinburger: One frustrating reason: I haven't found an idea with a sufficient chance of success to justify my investment.It's frustrating because I have execution skills (I've launched 'startups' for larger companies), I could fund a small startup without external help and I have access to good design & technical talent. Am I being unreasonably risk averse? Lacking vision? Words of wisdom will be much appreciated!
