Be kind whenever possible. It is always possible.
Only the educated are free.
Be gentle to all and stern with yourself.
To know oneself, one should assert oneself.
By failing to prepare, you are preparing to fail.
Without hard work, nothing grows but weeds.
It's always too early to quit.
Well done is better than well said.
Always desire to learn something useful.
The dog that trots about finds a bone.
