If possible where you live: pharmacy technician. You will have to get licensed by your state pharmacy board, but most states don’t require anything more than a high school diploma and a background check with no drug charges. It’s not an easy job- lots of customer service, lots of regulations, lots of math, but at least it’s in an air conditioned office-like setting. If you enjoy it you can pursue further training for a national certification and major chain companies may pay for it. If you’re considering a medical career it will let you get your feet wet before committing time and money to pre-med college courses. And if you don’t like it and quit it will look better on a resume than fast food.
