That's right but people always always fail to understand that life is time. Whatever problem you are facing is just a matter of time it will surely end, Nothing lasts forever.
And the part of comparison is really annoying and pathetic because it causes more hard than good. But most parents and most people always feel that comparing their children with another helps to motivate them to do better and become better but they fail to understand it's only hurting and that it is going to have a very great negative effect on the mental health of individuals.

How wish they knew. I just wish a lot if people sees this and also try to change from comparing people and praise them more. Praises increases the confidence of an individual.
