St. Louis Community college offers a wide variety of continuing education classes. You can take anything from self defense, to CPR, to how navigate the internet.
Classes are relatively cheap and they do not last forever, so you don't feel like it's a huge committment to make by taking a class or two.
I definitely recommend, if you are looking to dabble in a new skill or want to take on a new hobby, to check the schedule of courses here and see if they offer something you might be interested in.
