The thesis is a formal document whose sole purpose is to prove that you have made an original contribution to knowledge. (J.W. Chinneck, How to Organize Your Thesis)

shorter proofs are not necessarily better ones; the shortest proof is always "left as an excercise for the reader" (L. Lamport, How to Write a Proof.)
