Be kind whenever possible. It is always possible.
By failing to prepare, you are preparing to fail.
Be gentle to all and stern with yourself.
Never complain and never explain.
Always desire to learn something useful.
Begin to be now what you will be hereafter.
Well done is better than well said.
Without hard work, nothing grows but weeds.
The dog that trots about finds a bone.
Wherever you are - be all there.
