I've previously read other Oatmeal books and really enjoyed the humour alongside the fantastically talented illustrations. With this one however, I was struck by how hugely cynical and pessimistic the author comes across. I understand the concept of happiness being rather a binary term, you either are or you're not happy, and this doesn't encompass the whole range of human emotions accurately. But the way it was delivered just left me feeling really deflated at the end of it!
