Trust Your Gut
The best advice Limor Fried has received.
LIMOR FRIED: The best advice I ever got was from another business owner. And he told me, only do business with people you feel comfortable with. If your gut is telling you no, no matter how much money don't do it because you're going to regret it and you're going to doubt yourself later. So never do it just for the money. Do it because you want to do it.
