I can, therefore I am.

Problems are not stop signs, they are guidelines.

Leap, and the net will appear.

The dog that trots about finds a bone.

If you think you can do it, you can.

Without hard work, nothing grows but weeds.

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

To know oneself, one should assert oneself.

Be kind whenever possible. It is always possible.
