If you think you can do it, you can.

To know oneself, one should assert oneself.

By failing to prepare, you are preparing to fail.

The dog that trots about finds a bone.

Never complain and never explain.

It's always too early to quit.

What you do today can improve all your tomorrows.

Leap, and the net will appear.

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