If you think you can do it, you can.

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

Begin to be now what you will be hereafter.

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

Be gentle to all and stern with yourself.

Leap, and the net will appear.

Without hard work, nothing grows but weeds.

I can, therefore I am.

It's always too early to quit.
