Most of the peoples around you are pessimist. They fail to see colourful, bright and joyful side of life. Not only such people waste their lives but also they keep discouraging others on trivial issues. Do not let yourself down; do not let your confidence broken by such small thinkers.
Make sure what you are doing is right and do it. No one in the world has done something worthwhile for which he or she is not criticised initially. However, those who remain determine and confident even after discouragement and criticism, always attain their goals.
Be positive and think big. We create things in two steps, first mentally and then physically. Therefore, to achieving big, thinking big is very important. Negative thoughts drain your energy and destroy your confidence. Be an optimist.
