I'd agree with clockwerk here.
Some possibilities though, if you're a versatile and outgoing sort? Bar work would be okay, especially front of house. Back of house is boring outside of being your sole job and you'll wonder why you're even doing it instead of slinging freight or picking and pulling tickets for a warehouse. I mean, unless you LIKE prepping a kitchen or cooking on a line, more power to ya. If you're a server or tending bar, there are a bunch of opportunities to stack up and slap poon too. That's nothing to sneeze at. You'll also keep your social skills sharp and get paid while you're doing it.
If an actual side hustle that has the potential to replace and surpass your income is more your thing, look into getting a real estate license or getting into medical billing. You could also be a loan originator, sell insurance, become an underwriter, etc... This type of work typically isn't the kind of work where people care how many hours you put in and quotas vary (if there even is one). Sometimes I swear certain organizations just want someone to sit in a desk so the place doesn't look empty and non operational when people step in. The barrier for entry is surprisingly low. You won't really make much starting off, but if you've got good discipline and willingness to sacrifice for about 18mo, the payoff can very well replace and surpass your current income.
One of my best mates is an underwriter for the city and he gets to watch some GNARLY footage. Some people refuse to take those 'dirty' claims because it causes mental/emotional trauma to watch some camera footage. Those 'dirty' claims typically pay more, naturally due to actually being 'life and limb.' People generally have an inclination to sue if they're hurt or lost a loved one due to negligence and someone has to handle it. Why not you?
Personal training is another thing you could do if you've got the stones for it. If you're experienced in any hand to hand combatives, you may also consider teaching self defense. Women FLOCK to that if it's advertised the right way. (That's what I do.) With the way society is trending on how 'creepy' men are the marketing nearly does itself. lol You just have to switch your political and religious brain completely off and be an instructor. Then collect checks.
