I think, it is important to know and we should find it out what we are in reality. If we know, we can try at least to correct ourselves/ our behavior/attitude. Honestly, I am neither brave nor coward but I am tend to worrying badly! And, I hate to see me in this situation. I, of course, want to get rid of it!
Today, I searched on net and read about how to be brave and bold! I read,'' Worry does not contribute anything to a situation, it only robs you of the ability to enjoy the present moment.''
