To know oneself, one should assert oneself.

What you do today can improve all your tomorrows.

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

The dog that trots about finds a bone.

Always desire to learn something useful.

Be gentle to all and stern with yourself.

Problems are not stop signs, they are guidelines.

Leap, and the net will appear.

By failing to prepare, you are preparing to fail.
