Never complain and never explain.
Be thine own palace, or the world's thy jail.
If you're going through hell, keep going.
Well done is better than well said.
To be a good loser is to learn how to win.
The secret of getting ahead is getting started.
Without hard work, nothing grows but weeds.
If you think you can do it, you can.
Go for it now. The future is promised to no one.
The wise does at once what the fool does at last.
But I don't think we'll go there until we go back to the moon and develop a technology base for living and working and transporting ourselves through space.
