By failing to prepare, you are preparing to fail.
Be gentle to all and stern with yourself.
If you think you can do it, you can.
If you've got a talent, protect it.
To know oneself, one should assert oneself.
Without hard work, nothing grows but weeds.
Always desire to learn something useful.
It's always too early to quit.
Only the educated are free.
I can, therefore I am.
The precondition to freedom is security.
