One possible guiding framework:
1) Moral clarity - Not everything is relative. Right and wrong exist; discover which is which (in your mind), and how to tell the difference. Incorporate this into your core beliefs. Trust your gut. Wield an intransigent mind. Pushing the limits of conformity and mediocrity is an important part of human existence.
2) Human nature - Learn to recognize and anticipate the patterns in what causes people to do (or not do) things. This has changed very little throughout recorded history. Improving your understanding -- I mean brutally, honestly acknowledging what makes people tick -- will serve you well.
3) Critical thinking - Spend a little time learning about logical fallacies, and the other clever methods humans use to delude themselves and others. Critical-thinking skills are both an inoculation against being misled, and also well serve the other principles above.
Beyond that, the rest will come more easily. You will have strengths and weaknesses, in proportion. You will pursue subjects that interest you. You will have problems along the way, but you will be guided by a framework (perhaps even something vaguely resembling this framework... or another... or your own).
If you find receptive people along the way, gently teach them what you have learned... and then do not become too disappointed when they do not learn. *You* know it, and that is the most important thing.
One more thing: Do not feel guilty or sad about existing on Earth. This is all for you, as much as it is for anybody or anything else. The best revenge is living well... by which I mean, a culture of life - living your way, to serve your values, and ignore the herd.
I wish you the best of luck.
