It's always too early to quit.

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

You never know what motivates you.

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

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

The secret of getting ahead is getting started.

Be gentle to all and stern with yourself.

Always desire to learn something useful.

Begin to be now what you will be hereafter.
