Ech, can't shake the feeling that i'm wasting my life.
A little late to the party (lot of good advice above), but gonna second a few things.
I took a few years off from college to job around, and it was a really valuable few years of my life. I met a lot of good people, and a lot of bad people, and had a good variety of experiences that helped me to learn and grow. Because I worked at a restaurant, I learned how to calm down and communicate with Very Upset People, and had a chance to perform with a band at a few local gigs. I worked at a pet store, and met a guy who changed my life, taught me a ton about myself, introduced me to a ton of cool experiences I never would have had otherwise, and helped me find the inspiration to teach myself creative skills. Because of that jobbing period, I eventually realized I didn't want to complete the degree I was studying for, or live a traditional Climbing the Corporate Ladder life... and that I would rather focus on making my own career in a creative field.
Also... yeah, I think you kinda got to decide the terms on which you want to live your own life, and what makes a day Well Spent. And once you have a sense for that, to pursue that in your life, whenever you can. Sometimes, it's good to take some time to think in a holistic way about what you want out of life (everything, including food, money, shelter, friends, experiences, other things you find fulfilling or important, etc), and chart out paths that bring as many of those things as possible into your life. I know these are kinda vague terms, but these are terms you've got to figure out for yourself.
