I can, therefore I am.
Be gentle to all and stern with yourself.
Leap, and the net will appear.
Without hard work, nothing grows but weeds.
To know oneself, one should assert oneself.
Well done is better than well said.
The wise does at once what the fool does at last.
It's always too early to quit.
The most effective way to do it, is to do it.
Always desire to learn something useful.
