Thomas Edison tried 10,000 times before the light bulb worked. Henry Ford went bankrupt three times before succeeding. R.H. Macy failed several times before his department store took off. John Creasey got 753 rejection letters before he got through to a publisher for his first work. He then published 564 books.
Winners fail all the time.
They just don't stop at failure. They go for it, and then just keep going until they succeed. Go for what you want, and don't stop going. Start by getting clear on what you want and writing it down Then risk the failure and go for it.
