I can, therefore I am.

Without hard work, nothing grows but weeds.

Begin to be now what you will be hereafter.

Either you run the day or the day runs you.

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

If you're going through hell, keep going.

Always desire to learn something useful.

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

Wherever you are - be all there.
