It's easy to answer this question straight away....but wait...
believing in ourselves can be seen in two major extreme situations....
...when nothing is working right.
...when everything is ok.
Hope do you react to such situations?
When nothing is ok, do you crib and cry?What is the first thought that comes to your mind?That you are no good or that you could have done better or that you will do better.This shows attitude towards life.
But there's a second aspect to be considered...when everything is ok, rather when everything is perfect...what then?What do you feel?Surprise?Shock?Or a sense of peace that you got what you deserved?
Or consider when someone praise you..what is you reaction?Deep inside do you believe it or do you feel they are misguided?The answer to this shows your faith in yourself.This second question was the reason i realised having faith in yourself mean a great deal more than just staying up when things aren't working well.
