The dog that trots about finds a bone.
By failing to prepare, you are preparing to fail.
If you think you can do it, you can.
Well done is better than well said.
Be gentle to all and stern with yourself.
It's always too early to quit.
If you're going through hell, keep going.
To know oneself, one should assert oneself.
Be kind whenever possible. It is always possible.
The secret of getting ahead is getting started.
