Pick a mentor and what else

Q. What else?

Pick a mentor and ride his (or her) wave.

Every meteor revolves around a star. Similarly, you need to pick a successful person making money online in the path you chose earlier, contact that person and get them to take you under your wing.
You can find these people in forums such as DigitalPoint , WickedFire , SitePoint and WebMasterWorld.
Be very honest about who you are and what you are looking to do. Explain you are willing to work very hard for very little or no compensation, you are very impressed with the posts posted by [your chosen mentor] and are looking to learn more about making money online.
Don't expect to win over stars who are making 7 figures on-line. Start with folks who are just one level ahead of you in the game, re-assure them your intentions are pure and keep trying until you find the right fit.
Just about every successful person in both the online and offline worlds had a mentor they looked up to when they got started.
