The secret of getting ahead is getting started.
If you think you can do it, you can.
It's always too early to quit.
Only the educated are free.
The wise does at once what the fool does at last.
Do not weep do not wax indignant. Understand.
After a storm comes a calm.
I can, therefore I am.
Never complain and never explain.
To know oneself, one should assert oneself.
