Refuse to be ill. Never tell people you are ill; never own it to yourself. Illness is one of those things which a man should resist on principle.
The strongest principle of growth lies in human choice.
If you think taking care of yourself is selfish, change your mind. If you don't, you're simply ducking your responsibilities.
Prove all things; hold fast that which is good.
A doctor saves lives -- It's up to people to create lives that are worth saving.
Worries go down better with soup than without.
To repeat what others have said, requires education; to challenge it, requires brains.
