Never complain and never explain.
Be kind whenever possible. It is always possible.
If you've got a talent, protect it.
If you can dream it, you can do it.
By failing to prepare, you are preparing to fail.
If you're going through hell, keep going.
Either you run the day or the day runs you.
It's always too early to quit.
Begin to be now what you will be hereafter.
Well done is better than well said.
I think America has more than enough maturity and intelligence to start exercising its world leadership responsibly.
