It's always too early to quit.
Either you run the day or the day runs you.
Well done is better than well said.
Begin to be now what you will be hereafter.
If you've got a talent, protect it.
Problems are not stop signs, they are guidelines.
Quality is not an act, it is a habit.
Be kind whenever possible. It is always possible.
Always desire to learn something useful.
Know or listen to those who know.
