Teahouse of the August Moon (1956), starring Glenn Ford and Marlon Brando is a pretty forgettable film except for the fact that Brando is trying to play an Okinawan. However, I remember a very meaningful quote from the film, "We move in the direction of our dominant thought." If we think that we are a failure, or life is shit, we will move in that direction and we will end up in a negative place and all those bad things we are thinking about will happen to us. Positive thoughts and self-confidence move us in a positive direction and a realisation of those thoughts. Besides, if you do not bleieve in yourself and your message, no one else will.
