All what we have to keep in my mind is that we are not going to be on the stage forever. The drama will come to an end one day and all the characters will disperse. So let's decide to play our role with full commitment and dedication, as being a critic won't help much in improving our performance.
Remember only those stay in memories forever who gave their best, not the ones who kept discussing about the rest.
Believe me, life is all about give and take
You cannot offer porridge and expect a cake!
