There are a lot of hobbies you can get into that can be started with little or not cost, or with equipment/materials you already own.

Figure out what interests you and see what can be done inexpensively.

With a phone or computer, there’s writing, music, programming, learning new skills, Wikipedia, Pinterest, et al. Maybe take your phone and start photographing stuff in your area that interests you.

Find someone who has experience in an area you’re interested in. People tend to like to talk about their hobbies and interests and they can tell you how easy or difficult it is to get started. They might even be able to help you get started.

Maybe find a volunteer opportunity that helps pad your resume. Like animals? Volunteer at a local shelter.

There are a bunch of job certifications you can train for online that can also help build your resume.
