Be thine own palace, or the world's thy jail.
If you can dream it, you can do it.
Be kind whenever possible. It is always possible.
I can, therefore I am.
Without hard work, nothing grows but weeds.
Always desire to learn something useful.
You never know what motivates you.
The wise does at once what the fool does at last.
Only the educated are free.
Expect problems and eat them for breakfast.
Science by itself has no moral dimension. But it does seek to establish truth. And upon this truth morality can be built.
