I don't have "career" experience but I have low wage job experience:
-McDonalds.
Makes you work on holidays and you don't get extra compensation (you're not allowed to request holidays off). Customers treat you like shit because working in fast food means you're subhuman. The money isn't worth the type of daily crap you put up with. The management is terrible and turnover is higher for them than for actual working employees. It quickly sucks out your soul, life, and hope.
If you need to stay in fast-food, you should consider shifting to Starbucks, at least. Work environment is decent, you get good benefits, and aesthetics/etc are way more positive than a McDonald's would be. From what I hear, McDonald's especially is pretty bad.

I have had actual 'careers' in the past, which I could write about if anyone's interested, but I left them because I didn't want to be in an office environment/uber-corporate culture / at a desk / at a computer any longer, and had gotten myself into a bad box of being in more of a BA/PM role, which I really really hated.
--------
I'm currently at Starbucks, 'just' a barista, but, it has lots of positives that my desk jobs didn't have. I don't have to pretend that I'm wanting more responsibility and wanting to 'move up', I am able to be on my feet, moving around, doing stuff, for most of every day (which I love), I can interact with people a lot more and I enjoy bantering with my coworkers, even if on the negative side on bad days I really, really, really, REALLY feel my age (working with mostly 17-24 year olds), and I love the flexible schedule. I have the benefit though of being in a pretty functional store / great team, with great manager. I consider myself lucky... I know other stores can be different/far worse.
Downside is the small % of customers who are total assholes, the fact that some of my coworkers are pretty immature and dramatic (due to young age / still figuring things out I think), though that doesn't bother me per se, and low wage. But hey, I knew that going into it so the low wage was my choice. Also, too, I am seeing over time that it too has quite the strong corporate element, it's just not as obvious, or is of a different vibe/sort, than corporate financial institutions which I had previously been in. So the corporate hand in policy can take a toll on me/ in the work experience.
/ still figuring out life
I should also add that bigger-picture, it's of more importance to me to try to build my art/photography, and have more income coming in through that. The challenge of that is possibly the same as what you run into with your music, [MENTION=14857]fia[/MENTION] -- stable income, building an audience, and having income coming in at all through that outlet. For me, the ongoing thing is to try to figure out the marketing / web presence side of things, which I may need to outsource at some juncture just because it's not at all my skillset.
