We should be like how we think we are and not others think what we are Chithra V R

The exact and effective thing you need to do is finding out what energizes you. What gives you a positive impact while you are doing it. What keeps your mind immersed in the pool of joy and satisfaction. 

Just love the way you are. The key to self confidence is nothing but loving yourself, caring yourself. Try to be the bests version of you each each day.
