Hating yourself is a full-time job, so it's okay to quit Best Buy and go on the dole. Instead of hustling camcorders and small appliances, spend your day harping on every stupid thing you've ever said and done, eating non-stop carbohydrates and losing respect for everyone who isn't repulsed by you.
Hating yourself too much is better than loving yourself too much, because that can lead to hand cramps.
