Keep looking at your thoughts and separate your original ones from those that come from others or from books. Analyze your motivations and desires. Take care of your desires by fulfilling them through fair means and hard earned fruits of life. Refine your motivations.
Analyze what you like most and when you are happier than rest of the times. Think what situations make you feel better and what make you feel uncomfortable. Never decide under persuasion, greed, pressure or shyness. Be on your own and take your decisions yourself. Never worry on what others would say or how the world would look at you because of your failure or success.
I think if you can reach this level first at least in your worldly life, rest you will know how to handle.
