YouTube has a lot of videos about side hustles and remote work from home jobs.
If you are tech oriented, you could be a content creator. If your skills extend to producing videos, you could be a YouTube editor. It's kind of hard to offer suggestions because you haven't said much about what your background education and skills are.
I'm a lot older than you are. I'm 63. I just retired after having been a teacher for 32 years. I loved the first month off work. I tolerated the 2nd month. I'm now thoroughly bored. Since I have been both an elementary teacher (17 years) and a high school teacher (15 years), I am retraining as a special education teacher with an endorsement in autism and look to be heading back to work during the 2023-2025 school year.
I decided to stay in education because teaching is where my skillset is.
