If you're going through hell, keep going.

Never complain and never explain.

I can, therefore I am.

The secret of getting ahead is getting started.

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

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

What you do today can improve all your tomorrows.

By failing to prepare, you are preparing to fail.

To know oneself, one should assert oneself.
