Good choice! That sums me up. I hate pessimism. Too tiring! Always look on the bright side of life. Di dum, di dum, di dum, di dum. (Life of Brian in my head now!)
That's a bit like teaching, don't you think? If you don't try and get through to a resistant student who displays all the wrong behaviour but underneath wants to be understood and the satisfaction of achieving that and seeing them do well in their future. Can't beat that?
