I can, therefore I am.

To know oneself, one should assert oneself.

Well done is better than well said.

You never know what motivates you.

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

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

Problems are not stop signs, they are guidelines.

If you think you can do it, you can.

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