I can, therefore I am.

It's always too early to quit.

The most effective way to do it, is to do it.

Be thine own palace, or the world's thy jail.

If you've got a talent, protect it.

Either you run the day or the day runs you.

What you do today can improve all your tomorrows.

You never know what motivates you.

To know oneself, one should assert oneself.
