your parents would have passed on their hurts and prejudices to you....Comes a point in time in your own adult life when you realize that you are reacting unreasonably to some things - you are, in fact, reacting the way they do, but out of the context in which they reacted to those things. Think....for we live in an age where a great deal of knowledge is easily available via the Net on every subject. There is a lot of emphasis on right thinking....thinking that will help you lead a happy and fulfilling life (and by happiness I don't mean the he he ho ho variety of happiness, but that deep feeling of contentment that fills and warms your being)...and thinking that will bring peace of mind...
Then, discard those ways that have been handed down and that you have been blindly following, for they will only bring you grief....worse and worser...they will twist your mind into something which is not your own unique self.
Don't blame your parents....it is very easy to do so....for in all possibility they too were carrying on what was passed on to them without examining them...In your life you can examine and discard what is hurting you or blocking the real you, and choose what will help you a) create your own unique life b) create an aura of happiness or real freedom around you.
