This sort of narcissism is insulting to anyone to whom it's directed. A child wants to easily complete the big showy job and garner the praise.
If you can sleep well knowing you did the best you could do to make a contribution, that will bring you satisfaction. Praise from others is empty even if deserved it will never be enough by itself.
My father's profession was at one time regarded as the 'save the world' kind of thing. But he just wanted to provide a service to those who needed it. Black, White, Rich, Poor, Pay me or don't--his duty was to serve and the respect he *earned* in the community over many decades was through service, not 'saving the world'. He never sought praise as fulfillment; outside of his work where it was required, he didn't put letters in front of his name.
He taught me whatever I do I should do well. If I dig ditches for a living (great grandfather did), then I'd better be the best damned ditch digger I can.
