If you're very motivate or lucky you might find something you love no problem. Generally most people start out with jobs they don't like that much.
Dishwashing is good. Free food not super complicated you can work nights after school like fridays or something.
The biggest thing I can tell you is to work hard at every job and leave on good terms. If you hate a job you don't have to do it for ever, find something else and leave. What you shouldn't do is show up late, be a douche, not get things done, and leave on bad terms.
If you leave every job on good terms when you apply for a job you like, those references are going to come in handy. Also down the line if you need some work quick with one of those previous employers also very helpful.
Probably my least favorite job ever was checking tickets at a mountain after I shattered my collarbone/couldn't work park crew. I doubt my boss or any of the customers though anything other than I loved the job as I made the best of things. If I wanted to go back to work at that mountain later on or use them as a reference for a future job, I know I have 1 more solid reference.
Also it's nice having a little bit of money at a time when nobody really has any money. Even the little things like food, going to the movies, or whatever else kids are doing these days it's nice to have some $$$.
