“You have no responsibility to live up to what other people think you ought to accomplish. I have no responsibility to be like they expect me to be. It's their mistake, not my failing.”
― Richard P. Feynman, Surely You're Joking, Mr. Feynman!: Adventures of a Curious Character

“Success is not final, failure is not fatal: it is the courage to continue that counts.”
― Winston S. Churchill

“I think it's much more interesting to live not knowing than to have answers which might be wrong. I have approximate answers and possible beliefs and different degrees of uncertainty about different things, but I am not absolutely sure of anything and there are many things I don't know anything about, such as whether it means anything to ask why we're here. I don't have to know an answer. I don't feel frightened not knowing things, by being lost in a mysterious universe without any purpose, which is the way it really is as far as I can tell.”
― Richard P. Feynman

“Knowing yourself is the beginning of all wisdom.”
― Aristotle
