It's always too early to quit.
If you think you can do it, you can.
Without hard work, nothing grows but weeds.
Never complain and never explain.
Begin to be now what you will be hereafter.
Things do not happen. Things are made to happen.
To know oneself, one should assert oneself.
The wise does at once what the fool does at last.
If you can dream it, you can do it.
If you've got a talent, protect it.
It often takes more courage to change one's opinion than to keep it.
