Never complain and never explain.
Be gentle to all and stern with yourself.
Always desire to learn something useful.
Begin to be now what you will be hereafter.
The dog that trots about finds a bone.
The wise does at once what the fool does at last.
If you've got a talent, protect it.
Go for it now. The future is promised to no one.
Expect problems and eat them for breakfast.
After a storm comes a calm.
We learn more by looking for the answer to a question and not finding it than we do from learning the answer itself.
