I believe that we must purify our hearts, minds and eyes. Many times what we think and what we say is a negative result of our personal experiences which should never be generalized as a current logic for all the world. Let us see the good in everything and be an optimistic person. My dear friend , look for the positive, think positively, see the positive side of everything and I'm sure you'll find the entire world positive. Remeber when you go to a party, you say "I want to enjoy this happy moment" It's right! this short life is like a happy moment in a party, so enjoy it in a right way before it is finished!
