Basic research is what I'm doing when I don't know what I'm doing. Common sense is instinct. Enough of it is Genius. Don't be so humble. You're not that great.
Genius is one per cent inspiration and ninety-nine per cent perspiration.
Goodness is the only investment that never fails. He is happiest who hath power to gather wisdom from a flower. He that would perfect his work must first sharpen his tools. He who is sorry for having sinned is almost innocent. He who wonders discovers that this in itself is wonder.
