It's always too early to quit.

You never know what motivates you.

To know oneself, one should assert oneself.

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

The secret of getting ahead is getting started.

Things do not happen. Things are made to happen.

Only the educated are free.

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

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