You can learn and take advice from people who have succeeded and who have failed. Success is subjective. I define my success. some people attach success to money. Some people attach success to fame and popularity. It's all about what you are personally searching for, it's your life you have to live it. Don't let anyone live their life through you by forcing their definition of success. Take advice, learn from others, take it all in and then you decide what to keep and what's not right for you. Most of all pray, keep the faith, and love God.
