Never regret. If it's good, it's wonderful. If it's bad, it's experience.
The shortest distance between two people is a smile.
A little sincerity is a dangerous thing, and a great deal of it is absolutely fatal. - Wilde
Don't make promises when you're joyful. Don't reply when you're sad. Don't make decisions when you're angry.
If you don't like something, change it. If you can't change it, change your attitude. Don't complain.
