My humble advice – find a mentor. Someone who has been doing whatever it is that you want to do, for a LONG time. Ask him for help, ask him to take you under his wing. Shadow him, learn from him, learn from his mistakes, LISTEN to him, ask a million questions, do everything he does. Read as much as you can from books. Take classes and seminars. Ask more questions and LISTEN to his advice.
Mentor – from Webster’s dictionary - A wise and trusted teacher or counselor.
