I’m going to do something that I’ll probably regret again.
Unlike some myths that abound about VC’s:
I don’t know everything about everything.
I probably don't know anything about anything.
Maybe I get access to a mystical website when I finally start my own fund. But for now, I know enough to make a reasonable decision.

And when I don't know, I ask. Contacts, other investors, domain experts. This is why I can not sign an NDA. If I can't ask I can't be of any help as an investor. You don't have to be a genius to be a VC. But you know, this job might be easier if I was.
