Never complain and never explain.
You never know what motivates you.
Be gentle to all and stern with yourself.
Expect problems and eat them for breakfast.
The wise does at once what the fool does at last.
Who seeks shall find.
If you're going through hell, keep going.
To know oneself, one should assert oneself.
If you think you can do it, you can.
Either you run the day or the day runs you.
Exercise is the chief source of improvement in our faculties.
