Has anyone stepped away from their business and started it back up?

Has anyone done this?

For context, 4 years ago I took a pretty big risk, sold everything, moved in my parents basement, bought a commercial property which I started in the self storage business and it’s for the most part hands off, other than maintenance on the property and handling move outs.

I also started a powder coating business because the property had a shop on the property as well, all while I’m still working full time at my main job, basically I bit off more than I can chew and need more equipment to speed things up.

I’m pretty decent at it and had great customers but I think the whole working 90-100 hour weeks has burned me out last year.

I’ve talked to my dad about it, he thinks I should rent my shop out for awhile and comeback to it when I’m ready again. My fear is I pack it up and never return to it. I have a good job, passive income but again I’m working for someone else.

I know there is usually a wall you hit before you become successful enough to quit your job.

Part of me wants to keep going for it because I don’t want all the work I’ve done to go to waste but then again part of me feels the need to take a break and keep the storage rentals going and maintain it better.
