Working for yourself is not for everyone, many prefer the safety of easier jobs or even government jobs for hunting as they get a lot of time off and don't really have to worry about the $ side of running a business, getting fired, shitty work, or work long hours. It sounds like you have a kinda rough job. If you really want to hunt I'd say go for a government job. I have an office across from the USDA office here in Laramie and on any given day less than half the people are actually at work to give you an idea, and that was before covid. You see how much some of the guys on here hunt and many work government jobs for that exact reason. Lots of time off is good for hunting as is getting every holiday down to Columbus day off to go hunt or fish.
That being said I could never imagine working for someone else. I am like you and knew how to weld and ended up starting a business manufacturing skull hangers which has turned into my primary income. I started by myself and now have a team that keep sales moving on the various platforms, website, online advertising, welding, etc.. I like it as the sales roll in even when I am not working or awake versus only getting paid when you are actually working. I also like working with hunters so this was a perfect fit. But it is not good for hunting as my busy season is hunting season. I usually hunt a few afternoons at best. So if you do start your own business with the intent to hunt find an industry that is busy in the spring or summer as opposed to the fall.
I grew up in an entrepreneurial family and have always owned my own business and now own 2. I'm in the process of training someone to run my skull hanger business so I can focus on my other business which is my real passion right now. Owning your own business can be really rewarding as my second business was just accepted into a business accelerator through the Department of Energy which would never be possible working for someone else. That's what makes me tick. But it's risky, and can be financially tough when you have a family to support.
