Making mistakes is human ... repeating 'em is too.
The more sympathy you give, the less you need.
Once you've given advice to someone, you're obligated.
The biggest mistake people make in life is not trying to make a living at doing what they most enjoy.
If you say what you think don't expect to hear only what you like.
Thinking well to be wise: planning well, wiser: doing well wisest and best of all.
