Mark, a friend of yours, has always had a nagging desire to be his own boss. He has a good job with AT&T but has several ideas for new products that he can’t get AT&T interested in. Mark has done a good job saving money over the years and has over $100,000 in the bank. He asks you, “Am I crazy for wanting to leave AT&T to start my own businesses? How do I know that I have what it takes to be a successful entrepreneur?” What would you tell him?
