Deciding what you want to do in life is instrumental to success. Obviously, the more passion you have in something, the more likely you will succeed. There is nothing at all worse than being forced or stuck in doing something for the rest of your life that you really don't want to be doing.
That leads to my second point: finding a life goal. I don't mean something like becoming a celebrity. I mean something like religion or martial arts; no matter how good you get, there is always more to go. That way, you ALWAYS have a purpose in life. That is the main problem celebrities have.
Lastly, always have a back up plan. If your passion is to become a musician, most likely you won't make much money. Always have something on the side. Such as a business degree or something.
That's about it. If you follow those tips you should be pretty well off.
