Well, chopping is one thing, but what about "finely" chopped? That's the one I dread the most!
Whenever I can get away with it, I do coarsely chopped, which is okay when melted over a double boiler, but not an option when pouring hot cream over the chocolate in a bowl, and stirring till melted, as in a ganache. And to make matters worse, with that method, I'm sometimes left with tiny pieces, after all the tedious, fine chopping. Ugh - I hate that.
