I did that years ago, unintentionally.

I had been unemployed and got a gig teaching at night, it was only supposed to be a temp gig. 6 PM to 10 PM M-Th.

I couldn’t make a living doing that, so I kept looking and landed an 8-5 gig in my field.

Then the temp gig wanted to keep me on. 🤷‍♂️

So, for way longer than I should have, I worked my main job 8-5 and taught from 6-10 M-Th. 56 hour weeks.
