almost all the problems
Try to think for a moment, almost all the problems in your life most likely happen because we are too baper and tend to ignore the logic / mind. We always feel that we are the center of this world (self center), we always assume that our feelings are the most important existence in this life which is true and also wrong, true because naturally everyone thinks he is the most important because this is our own life, wrong because in fact your feelings are not important at all for the world and others.
