I can, therefore I am.
Without hard work, nothing grows but weeds.
The wise does at once what the fool does at last.
The dog that trots about finds a bone.
If you've got a talent, protect it.
If you think you can do it, you can.
It's always too early to quit.
The secret of getting ahead is getting started.
To know oneself, one should assert oneself.
Be gentle to all and stern with yourself.
Be good. Do good. The devil wields no power over a good man.
