To know oneself, one should assert oneself.

Be gentle to all and stern with yourself.

It's always too early to quit.

If you think you can do it, you can.

Expect problems and eat them for breakfast.

Never complain and never explain.

Do not weep do not wax indignant. Understand.

If you can dream it, you can do it.

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