If the question is about the logics and rationale to be ambitious, then I would say... If you are capable of, it's good to know the peak in a 'been there done that' than to regret later on in life. Nobody can be doubly sure that they do not want to be ambitiously successful. We are all carbon creatures with a ageing embedded into our system. Once passed the golden growth stage, it is very hard to make a comeback for most.

If the question is poised in a spiritual or psychological manner, life is not delivering what others expect of you. Your life, you decide the purpose and find the meaning.
