1) always maintain a positive and happy attitude.
2) be as realistic as possible with yourself and as honest with others as possible, i.e don't bullcrap around by thinking of concepts and religions.
3) get rid of the "belief" system. What I mean is to just stop with the damn "I believe", "that's my opinion", "I believe in", and realize belief in ideas/religions/concepts that do not do anything for you, or have any reasoning to them are non existant and irrelevant.
4) Stay physically and mentally disciplined.
5) Always be as merciful and compassionate as possible, exceptions are when a social injustice takes place.
6) NEVER conclude to anything you know...always be waiting for new stuff to add in to your psyche.
7) educate yourself on stuff that can be useful, which can include even "spiritual" practices such as healing affirmations, or holistic eating, good doctors, what's really going in politics and the world without getting sources through incomplete media programs.
