Never complain and never explain.

Be gentle to all and stern with yourself.

Without hard work, nothing grows but weeds.

The secret of getting ahead is getting started.

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

Begin to be now what you will be hereafter.

It's always too early to quit.

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

What you do today can improve all your tomorrows.
