There comes a time when you stop caring what others think about you and you accept yourself the way the One God Almighty has created you. That is when you set yourself free and start living in the true sense. I believe that a person should know what he is made up of, I mean his strengths and weaknesses, and love the way you are. And when you do that it does not matter what the world thinks about you.
But, not caring about what others think about you does not mean you have got the license to do as you please. In fact, you should still take care that you don’t harm yourself or hurt the feelings of others when you live life according to your own rules.
