I think entrepreneurs/founders are inundated with so much advice from every direction that their brains train themselves to ignore all advice at the present moment and maybe give it a thought later.

This is actually a good thing since a founder needs to have capacity for independent thought but it misfires when the advice is from someone like pg.

My recommendation would be to consciously admit when you are doing this and then to consciously stop yourself from doing it when someone really knowledgeable is talking to you.
