“One's doing well if age improves even slightly one's capacity to hold on to that vital truism: "This too shall pass.”
“I suspect, even more importantly, the aged are hidden away so that we do not remember that one day we shall all walk that path, that we shall one day grow slow and stooped.”
“If one makes himself master of one vital book, he shall never become a commonplace man.”
“To explain all nature is too difficult a task for any one man or even for any one age”
“Today..passes as yesterday, today is passing by... Tomorrow shall become today and that too shall pass!”
“If I have the belief that I can do it, I shall surely acquire the capacity to do it even if I may not have it at the beginning.”
