The dog that trots about finds a bone.
Be gentle to all and stern with yourself.
Only the educated are free.
To know oneself, one should assert oneself.
To be a good loser is to learn how to win.
It's always too early to quit.
Go for it now. The future is promised to no one.
Always desire to learn something useful.
Things do not happen. Things are made to happen.
If you can dream it, you can do it.
Is it right to probe so deeply into Nature's secrets? The question must here be raised whether it will benefit mankind, or whether the knowledge will be harmful.
