Never complain and never explain.

I can, therefore I am.

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

It's always too early to quit.

Do not weep do not wax indignant. Understand.

To know oneself, one should assert oneself.

If you think you can do it, you can.

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

Problems are not stop signs, they are guidelines.
