It's always too early to quit.

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

To know oneself, one should assert oneself.

Never complain and never explain.

If you think you can do it, you can.

By failing to prepare, you are preparing to fail.

Wherever you are - be all there.

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

The dog that trots about finds a bone.
