I can, therefore I am.

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

To know oneself, one should assert oneself.

Without hard work, nothing grows but weeds.

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

The dog that trots about finds a bone.

Go for it now. The future is promised to no one.

Things do not happen. Things are made to happen.

Be kind whenever possible. It is always possible.
