1) try to get over yourself
It is very easy to become so absorbed in our own pursuits, our own circle, our own type of work, that we forget how small a part this is of the total of human activity and how many things in the world are entirely unaffected by what we do. In this excitement and overestimation of our own importance there is nothing desirable. True, it may make us work harder, but it will not make us work better.
2) try to get over yourself
Many active people are of the opinion that the slightest grain of resignation, the faintest gleam of humor, would destroy the energy with which they do their work and the determination by which, as they believe, they achieve success. These people, in my opinion, are mistaken. Work that is worth doing can be done even by those who do not deceive themselves either as to its importance or as to the ease with which it can be done.
3) no really, try get over yourself
Admit to yourself every day at least one painful truth ... Teach yourself to feel that life would still be worth living even if you were not, as of course you are, immeasurably superior to all your friends in virtue and in intelligence.
The secret of happiness is this: let your interests be as wide as possible, and let your reactions to the things and persons that interest you be as far as possible friendly rather than hostile.
To ignore our opportunities for knowledge, imperfect as they are, is like going to the theater and not listening to the play. The world is full of things that are tragic or comic, heroic or bizarre or surprising, and those who fail to be interested in the spectacle that it offers are forgoing one of the privileges that life has to offer.
The happy man ... feels himself a citizen of the universe, enjoying freely the spectacle that it offers and the joys that it affords, untroubled by the thought of death because he feels himself not really separate from those who will come after him. It is in such profound instinctive union with the stream of life that the greatest joy is to be found.
