Lust. But in the old sense of the word. It didn't used to just signify sexual desire, but simply desire itself. Desire for wealth, power, fame, possessions. It describes me perfectly, I believe I was born with the heart of a Ceasar, I want EVERYTHING.
I lust after James Franco and Paul Newman. I'll eat an entire sack of clementines over a weekend or a tub of hummus in a day, so there's gluttony. I like sleeping for nine to ten hours a night, so there's sloth.
Probably pride or greed. I'm leaning towards greed though, as while there are some aspects about myself I feel are sometimes gloat-worthy - I actually spend almost as much time wishing I was somehow different or better. I think that's more of an artist mentality anyway - we naturally hate ourselves, but we feel as if we are still better than all those who surround us So I might be greed. I don't like spending my money on anything that I personally won't get some joy out of. I'm not very charitable and I have a "people should work for their own shit and solve their own problems" mentality whether they are victims or not - I hate the thought that my paycheck gets taxed every week to fund some lazy or just too-pathetic-to-work people I don't even know or care about whose life-issues shouldn't be my burden, or anyone elses for that matter, and I think helping people with a track record of incompetence or sheer laziness is just a waste of money and resources I'm not much of a sharer either - but that's mainly because of bad past experiences. Whenever I did share my food - everyone got greedy and I was still left hungry after having what was left of it. And when I shared items I could get back - I either got it back damaged, ridiculously late, or never at all. I can't help but feel that other people just don't enough respect for me or my stuff to benefit from either
In this day and age it shouldn't be, especially in modern western society since I would agree that anything we work and pay for should be ours to enjoy guilt-free, even if it is ridiculous amounts of expensive food that may end up being half-wasted anyway - it is still something we made sacrifices for to be able to enjoy if we want
But traditionally (when these "sins" were likely written) food wasn't as available or disposable as it is for western society today. It wasn't as easy as going to the grocery store and stocking up on food that has already been picked, cleaned, processed and packaged for you to cart out of there for a relatively low price (considering what goes into it beforehand). Availability of food was a much bigger deal then than it is now. A glutton back then could have really made a lot of others around them starve as a result of their own need for a bigger share of the limited food supply than what was needed for them to just to stay healthy
