One way to get tripped up is to get too wedded to the particular instance of an idea. 

You may have the right idea, but the instance is wrong. 

Hold an open mind for many instances of an idea not just one, especially in the early days.

This is a lot easier to do as an investor, and a lot harder to do as a builder.

investors don't have the same attachment to instances (as they deal with many simlutaneously in their port) vs builders mono-focused on their current instance
