You learnt that, whatever you are doing in life, obstacles don't matter very much. Pain or other circumstances can be there, but if you want to do a job bad enough, you'll find a way to get it done.
You learn to kid around and joke and not take things too seriously because somehow its all gonna work out for the best - or you're gonna make it work out.
Merlin really taught me how to concentrate, that you play each play as if it were the only play. And if you put all the plays together like that, then you'll come out on top.
