I can, therefore I am.
If you think you can do it, you can.
Problems are not stop signs, they are guidelines.
The dog that trots about finds a bone.
Go for it now. The future is promised to no one.
Always desire to learn something useful.
If you can dream it, you can do it.
Expect problems and eat them for breakfast.
Be gentle to all and stern with yourself.
Never complain and never explain.
I think that I shall never see a poem lovely as a tree.
