It's always too early to quit.

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

You never know what motivates you.

The secret of getting ahead is getting started.

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

To know oneself, one should assert oneself.

Without hard work, nothing grows but weeds.

Never complain and never explain.

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