I can, therefore I am.

Without hard work, nothing grows but weeds.

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

Problems are not stop signs, they are guidelines.

Begin to be now what you will be hereafter.

Things do not happen. Things are made to happen.

If you think you can do it, you can.

Always desire to learn something useful.

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