What side job or career can I learn or do in my spare time to earn money? - Lemmy.world

Hey guys. I own a fairly successful business that I built from the ground up, but I still find money is super tight. I have a child on the way, and I want to be able to provide for my family everything I didn’t have growing up. What career or side job would you recommend I do or learn in my spare time? I’m open to any suggestions. Thank you everyone!
