What beliefs to choose
In my previous notebook entry I wrote that we can choose our beliefs. A probable conclusion from this could be that we can believe whatever is convenient. But I don't like the idea. If we choose to believe something that is convenient but not rational this can cause problems in the future. For example, we can waste all our income and don't try to save or invest, believing that the government or a company will take care of us when we become older.
So, I prefer to choose beliefs that are at least not lies, better if they are based on facts and thought through.
Sometimes the best thing to believe, if we care of long term happiness, is not convenient at all and takes courage just to realize it. For example, sometimes bad traits of character can prevent us from moving forward if choose to believe that we are good and try to hide them from others and even ourselves. Another example, is some important decision that was made in the past and that turned out not to be good later. It can be very hard to confess that you have been wrong for such a long time.
So, for me, the key is the long term result of a believe and how truthful it is for us.
