Common sense is instinct. Enough of it is Genius. Creative minds always have been known to survive any kind of bad training. 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.
