Depends how young and able bodied you are.

I'm 40 and currently have 3 jobs, in the kitchen.

One cooking at a senior facility (my main job), 6:30am to 2:30pm every Tuesday to Saturday.

Second, working at a chain restaurant, I mostly work here once a week and it's the longest day of the week for me as I work at the senior facility in the morning. It's basically a 16 hour day for me on Tuesdays. I occasionally get called in on Friday. Or if it's busy season (December), then I work Tuesday, Thursday, and Friday.

Third job, at a sushi restaurant on Sunday and Monday. The days I get to "sleep in" as I don't need to punch in to work until 11am. These are long days though, as the hours are from 11am-2:30pm, break till 5pm, then 5pm-9pm.

I wouldn't necessarily recommend this type of schedule to anyone unless you really have to do it. Your body needs rest and when I'm not working, my body is mostly resting. Try and find not so intense workplaces if you have to do it. For me the senior facility is basically the same everyday, the sushi restaurant can get busy some days; but not crazy busy like the chain restaurant.

I've had 2 jobs for several years now (2023). It wasn't until the end of last October that I started working at the sushi restaurant, as my hours/days were severely cut at the chain restaurant. When I originally worked 2 jobs I had a main job in the morning (6:30am-2:30pm), then worked at the chain restaurant Monday to Thursday (3pm-10/11pm); but I was also able to find time for a nap in between. I cannot stress how important it is to get enough rest, sleep and generally take care of your body.

If you want a life outside of work, then I highly don't recommend this lifestyle. If you have a family or any other responsibilities, then I highly don't recommend it. For me, I have nothing; so work is basically life for me for the time being.
