Pick your battles when pitching

Arguing until the bitter end about small facts, when the VC thinks she right because she has a reliable source (in her opinion) is not a good idea. You might be right, BUT you will not convince her, you will do no good to your credibility, and you raise doubts about how the future CEO-Board Member relationship is going to pan out.

Better focus that energy in disagreements that are really worth arguing about. Pick your battles.
