I actually see this from a different angle. I think the bar is incredibly high, and that many investors fail to clear it. It is high because, when you see the best investors at work, it is blindingly obvious that they operate in a different way.

The strange thing to me is that many investors don't realize this is happening and just coast on the funds they've raised. Founders talk to one another constantly. They know who works hard and who doesn't, and orient themselves accordingly.
