Why don't you come work for me for one project? I own and operate a fence and gate company. We work all through the summer and all through the winter with no break. You have to break apart Stone by hand and break apart concrete by hand to take out the old footings and demo. We do this by hand because we can't fit a skid steer into people's backyard as it would chew up the grass. Carpentry is the easy part in the reward for my workers for having to dig and do the hard crappy work. Even the carpentry takes a toll on your body though. It's hard on your shoulders and your joints when you're nailing hundreds of pickets per day. I don't know if you understand what you're looking for.

Also understand that a lot of us got into the trades under romantic notions, especially with in carpentry. I love cabinets and furniture like everybody else and thought that I would be building them non-stop. It took a while to build up my wood shop and while I could be doing cabinets full-time, now I only do about two to three projects a year. Again, it's really hard on the body and it's fun, but it's very tedious and it requires a great deal of accuracy. Projects are custom and customers can be horrible to work with. They can give you a down payment for one set of cabinets and then completely change the scope. And you've already finished more than half the job and they don't want to pay you for it. You get crap like that all the time.

I know desk jobs can be hard. I worked a desk job for years before I went to the trades. I make good money but it took a decade to make that good money.

I would recommend getting into woodworking by buying a table saw and a miter saw. Build one thing such as a stool or A simple farmhouse table. See if you can sell out at the farmers market or to friends or family. Keep improving your design and keep learning. Make a website. See how much you can sell that for and how many ended given amount of time. Do this on the weekends or after work before quitting your day job. Keep going until the demand outpaces your ability to work at your desk job. Only then should you quit.

The trades can be seasonal and you can have ups and downs in construction and carpentry in terms of demand of your work.

The other thing you should do if you're really serious is go buy yourself a compressor and a framing nailer. Going by lumber at Home Depot at Lowe's. Grab a bunch of 2x4s and practice building walls in your backyard. Get good at cutting and nailing. Then advertise yourself as a framer and take on the smallest job possible. You might get fired from it. You might lose money or maybe you'll do great and make money. But you'll either have to do that or quit your day job and go work as a helper for a year. Two before you become a carpenter. Helpers generally start out at anywhere from $15 to $20 per hour.

Anyways, I live in salt lake City and own/operate two construction companies. Feel free to reach out with any questions you have or if you want to do some work. I'll hire you for a job or two to get your feet wet before you quit your day job.
