Came across this fact today, Howard Schultz ,Starbucks fame, approached some 275 odd investors to raise money for his first venture which was similar to starbucks. Of 275 potential investors,  260 investors said NO. Imagine a situation like that where you are been told NO , 260 times. I guess that is one key trait of any person who wants to build a successful enterprise..Getting used to taking NO as an answer and still not getting affected by it largely.
