You are your own best teacher. My advice is to question all things. Seek for answers, and when you find what seems to be an answer, question that, too.
Louis L'AmourDo not let yourself be bothered by the inconsequential. One has only so much time in this world, so devote it to the work and the people most important to you, to those you love and things that matter. One can waste half a lifetime with people one doesn't really like, or doing things when one would be better off somewhere else.
