If people aren't calling you crazy, you aren't thinking big enough.
Engage your emotions at work. Your instincts and emotions are there to help you.
Give your employees a mission that matches their ambitions. When you challenge people, they surprise you.
Never go into business purely to make money. If that's the motive you're better off doing nothing.
Do not be embarrassed by your failures, learn from them and start again.
Just watching Israel bombarding Palestine and Palestine sending one or two little rockets over to Israel - it's just too sad for words.
