The wise does at once what the fool does at last.
If you think you can do it, you can.
To know oneself, one should assert oneself.
Expect problems and eat them for breakfast.
Be gentle to all and stern with yourself.
It's always too early to quit.
Either you run the day or the day runs you.
Wherever you are - be all there.
Never complain and never explain.
Always desire to learn something useful.
We have found that where science has progressed the farthest, the mind has but regained from nature that which the mind put into nature.
