This blog post by Fred Wilson resonated with me.

Surrounding yourself with smart people is not enough to make (investment) decisions. Now that I am knee deep into coding applications myself, I finally start to understand technologies that I have been pitching in dozens of slide decks over the past decades.

I think it goes a bit further than Fred’s blog post. Really smart people (not saying I am) with MBAs (I have one), that work at prestigious companies such as McKinsey (I worked there) are extremely good at telling you why something will not work, and 99% of the time their arguments make perfect sense. It is very hard for these people though to commit to believing in something that will work. Advisors are not entrepreneurs.
