Well, the truth is at the moment I'm not. For the past few weeks I've barely been reading at all. And I'm miserable. I feel so uninterested and uninteresting. So I guess that's why I'm reading the classics: without them life is incredibly dull.
I think the common misconception is that classics are classics because they're difficult. Like they're some sort of entrance exam to an elite group of 'the educated'. But what I've found is that they're not. They're classics because they say something new about life and the way we live it. They're thought-provoking, they're inspiring and yes: sometimes they are challenging. But they are challenging for a reason, because it's difficult for something to challenge your views and to change the way you see about the world. The 'classics,' in my opinion are not, or shouldn't be, a definitive list - but an evolving compilation of the books that really change people.
'Books' are an escape, but true 'classics' are life altering. So I guess that's why I'm reading them.
