I can, therefore I am.

Things do not happen. Things are made to happen.

The most effective way to do it, is to do it.

What you do today can improve all your tomorrows.

By failing to prepare, you are preparing to fail.

Wherever you are - be all there.

Always desire to learn something useful.

To know oneself, one should assert oneself.

The dog that trots about finds a bone.
