I can, therefore I am.
If you think you can do it, you can.
Either you run the day or the day runs you.
The dog that trots about finds a bone.
Always desire to learn something useful.
Be gentle to all and stern with yourself.
The wise does at once what the fool does at last.
Wherever you are - be all there.
Know or listen to those who know.
Things do not happen. Things are made to happen.
When we are afraid we ought not to occupy ourselves with endeavoring to prove that there is no danger, but in strengthening ourselves to go on in spite of the danger.
