I can, therefore I am.
Without hard work, nothing grows but weeds.
If you've got a talent, protect it.
Always desire to learn something useful.
The wise does at once what the fool does at last.
The dog that trots about finds a bone.
Only the educated are free.
Well done is better than well said.
Do not weep do not wax indignant. Understand.
If you're going through hell, keep going.
