It's always too early to quit.
Go for it now. The future is promised to no one.
If you can dream it, you can do it.
Be thine own palace, or the world's thy jail.
To be a good loser is to learn how to win.
Be kind whenever possible. It is always possible.
Who seeks shall find.
The dog that trots about finds a bone.
Without hard work, nothing grows but weeds.
Always desire to learn something useful.
Science by itself has no moral dimension. But it does seek to establish truth. And upon this truth morality can be built.
