Hmm this isn't easy cause i don't do anything of these seven deadly sin in excess that would make me stupid and bring myself to ruin. So keeping that in mind here goes.
Pride: Hmm i do value myself, i don't expect to be the best or put others down. But at the same time, i know i'm good at some things, just not everything.
Lust: Not much to say here except that while i do have lots of desires of the opposite sex, generally i am to lazy to act on them cause most times when i do, it blows up in my face somehow. Say something stupid, etc etc.
Wrath: Stupid things get me shitty, whether it be stupid people or stupid ideas. I really get the urge to draw claws and try and rip it apart. Stupid plots piss me off.
Sloth: Hmm times i don't feel like doing anything and i'm just content to stay home and read a book, play games and let time move past me.
For the last three i would be make them equal value since i am not sure that i have these problems. Plus i don't feel they are superior to each other.
Greed: I live in the first world, i live comfortably and have no desire to accumulate for the sake of accumulating.
Envy: Envy implies i want what other people have. While i desire things and much as the next person, at the same time i'm not beholden to it and can do without. But again this is related what i mentioned in greed, i am content with my life. It could be better but at the same time it could be alot worse. Exception to this might be the desire for relationships and related stuff but again meh, i'm used to being single so i can live without. Not ideal but again whatever.
Gluttony: I like nice food, but i don't eat and stuff my face silly either. I'm happy that i'm able to eat good food and not be starving. I don't over eat.
