Be gentle to all and stern with yourself.
Know or listen to those who know.
Go for it now. The future is promised to no one.
Always desire to learn something useful.
It's always too early to quit.
The wise does at once what the fool does at last.
If you've got a talent, protect it.
Well done is better than well said.
If you can dream it, you can do it.
Things do not happen. Things are made to happen.
I guess happiness is not a state you want to be in all the time.
