Your decisions are yours and yours alone, you own them, so don't let anyone dictate what you should do and what not to do.
Some of us are victims of what people expect from us and what they say is right for us. They live their life to please others and they never stops doing what will make the other pleased.
But what about your own life, do you know what is right for you ? . do you do what pleases you ? ..
We are the owners of our decisions, so we should learn to decide for our selves. Just because John decides to go to a night party doesn't mean you must join him. You can still decide to do other things. i am not asking you not to go to night parties but over the years, i have observe that people will blindly follow their friends anywhere and abandon what they have decided to do at that time.
