“Whatever you do, the only secret is to believe in it and satisfy yourself. Don't do it for anyone else.”

“Whatever you say, old boy. Just look after yourself. And whatever you do, don't swallow the gum!”

“There are moments in your life when you see yourself through someone else’s eyes, when your only hope of believing you’re capable of doing something is because someone else believes it for you.”

“Don't mind anything anyone tells you about anyone else. Judge everyone and everything for yourself.”

“Focus on yourself -- do what you want, when you want, without having to consider anyone else's agenda.”

“… you realize that you don't understand yourself any better than you understand anyone else.”

“Nobody can hinder you from doing what you want, if that's what you set your mind to. You can always find a hook to hang excuses on, but they're only excuses. You don't have anyone to blame but yourself. Nobody else makes you fail.”

“You do it to yourself, you do,
And that's why it really hurts,
Is you do it to yourself, just you,
You and no-one else,
You do it to yourself.”

“Whatever you would make habitual, practice it; and if you would not make a thing habitual, do not practice it, but accustom yourself to something else.”

“Don't ever write anything you don't like yourself and if you do like it, don't take anyone's advice about changing it. They just don't know.”
