Sloth, definitely sloth. There are times when I feel that I might just be the very embodiment of procrastination. Thankfully, I can overcome this on very important matters, and I hope to keep doing that(and maybe even more) in the future.
As far as I know, glutonny means being unable to find moderation in food consumption. If we can broaden the concept to apply to other things, then this would take a strong second place. Whenever I discover books, music, games, tv series or movie series that I like a lot, I usually indulge myself too often and for amounts of time that border on unhealthy. It becomes all or nothing for me.
I think I'm actually pretty good with the other five.
Envy - yes, there are moments when I think that I'd like to have things or even character traits that other people have, but it's never in a malicious manner.
Wrath - I don't get into many situations that require anger managements, but when I do, I try to avoid venting on other people. I prefer punching a wall.
Lust - I like girls and I like sex. Though I think there's nothing unhealthy in the manner that I like them.
Greed - I'm sometimes stingy about money, but I think it's only in comparison to other people. I don't buy a lot of stuff for myself, just because I think I don't need most of it. I don't need the newest iPhone or iPad or iWhatever, I have a fully functional 5 year old Nokia N73 that I use for SMS, calls, camera, alarm, calculator and internet access(however outdated and crude, yet still effective).
Pride - I may not have the highest self esteem or ego, but I know my worth. I don't go around flaunting it though.
Uh, yeah. That about covers it.
