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

What you do today can improve all your tomorrows.

Wherever you are - be all there.

Know or listen to those who know.

Go for it now. The future is promised to no one.

The wise does at once what the fool does at last.

To know oneself, one should assert oneself.

It's always too early to quit.

Always desire to learn something useful.
