Things do not happen. Things are made to happen.
Never complain and never explain.
If you think you can do it, you can.
I can, therefore I am.
It's always too early to quit.
After a storm comes a calm.
Either you run the day or the day runs you.
To know oneself, one should assert oneself.
Begin to be now what you will be hereafter.
Well done is better than well said.
I don't really trust a sane person.
