It's always too early to quit.
To know oneself, one should assert oneself.
If you think you can do it, you can.
Begin to be now what you will be hereafter.
If you've got a talent, protect it.
Who seeks shall find.
The wise does at once what the fool does at last.
Be thine own palace, or the world's thy jail.
What you do today can improve all your tomorrows.
Only the educated are free.
One reason the human race has such a low opinion of itself is that it gets so much of its wisdom from writers.
