"Be sceptical, question authority, be a rebel. All human progress is the result of far-sighted people challenging orthodoxy, tradition and powerful, vested interests. Don't accept the world as it is. Dream about what the world could be - then help make it happen. In whatever field of endeavour you work, be a change-maker for the upliftment of humanity.”
I suppose you might argue that this is a little grandiose, especially that last sentence about the, um, upliftment of humanity. Also he should have added “and whenever possible, rip the piss out of Diane Abbott”. But other than that, fine words and good advice.
