Problems are not stop signs, they are guidelines.
If you think you can do it, you can.
What you do today can improve all your tomorrows.
To know oneself, one should assert oneself.
Never complain and never explain.
The wise does at once what the fool does at last.
Who seeks shall find.
Always desire to learn something useful.
Expect problems and eat them for breakfast.
Either you run the day or the day runs you.
In those parts of the world where learning and science has prevailed, miracles have ceased but in those parts of it as are barbarous and ignorant, miracles are still in vogue.
