of the human nature ... we are all imperfect and would always seek perfection. Sometimes it would take you somewhere else, you will end up falling into the traps of your soul ego or even worse ...

Try to be the best in what you believe and know that you are good at, but don't try to be someone else ...
That would take you from ambitious group to the dumb one.

Do not dwell in the past, do not dream of the future, concentrate the mind on the present moment. (Gautama Buddha)
