Without hard work, nothing grows but weeds.

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

Never complain and never explain.

Only the educated are free.

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

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

To know oneself, one should assert oneself.

It's always too early to quit.

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