Never complain and never explain.

You never know what motivates you.

If you think you can do it, you can.

Know or listen to those who know.

To know oneself, one should assert oneself.

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

What you do today can improve all your tomorrows.

Do not weep do not wax indignant. Understand.

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