I wonder if I’ve been changed in the night? Let me think. Was I the same when I got up this morning? I almost think I can remember feeling a little different. But if I’m not the same, the next question is ‘Who in the world am I?’ Ah, that’s the great puzzle!

Be what you would seem to be – or, if you’d like it put more simply – never imagine yourself not to be otherwise than what it might appear to others that what you were or might have been was not otherwise than what you had been would have appeared to them to be otherwise.
