I think there's a lot of emotional work that goes side-by-side with the physical when you're transitioning from one way of living to another. Like, for me, I've spent more years unlearning what I thought to be true than I did living it in the first place, and I've barely changed my lifestyle in all that time. So, coming at this from a different angle:
Just by being here, you've already started questioning the status quo. So I think the next step is pinpointing the areas that are making you the most unhappy, or areas that, by changing, will make you happier/ feel like you have the most agency in your decisions. Start with the smallest changes that will make the biggest impact TO YOU. The changes can be tiny and silly, like going barefoot more often or re-growing onion tops on your windowsill.
You might never be able to get your partner fully on board with your end goal, so it might be in your best interest to reevaluate what's ideal vs. what you're willing to concede. Ideally, any spouse is going to want to meet halfway and try something new and facilitate their partner's personal growth; best case they discover something new about themselves and you take that journey together. Worst case, they try to stop you from doing something that makes them unhappy, without regard to your feelings. For almost everyone, it's going to fall somewhere between those extremes. I think it's good if you (as the partner seeking change) have a clear idea of what you ultimately want and what you're willing to give up or trade-off to get it (or close enough to make you happy). Maybe your husband doesn't want to move to a sheep farm out in the middle of nowhere, but he'd be cool with a few hens and a kitchen garden somewhere on the edge of town, especially if there's ample space for him to explore one of his own hobbies or passions.
Also this: don't get caught up in what you think you "should" be doing. I have friends who are way more off-grid than I have any desire or ability to be. A lot of times I find myself in a shame spiral after I interact with them because I'm not as hardcore about XYZ thing as they are. Like, they buy tri-axles of whole logs for firewood and process it all themselves without a hydraulic splitter (all through 7 pregnancies!); I personally struggled maintaining the firewood for a 3-person household when it was delivered already cut, split, and seasoned. DO NOT hold yourself to anyone's standard but your own. Part of being more resilient and self-reliant is learning your strengths and your limits and living within them, even if they don't look like what you thought they should. I've watched videos of hardcore off-gridders pulling their own teeth because they don't want to (or can't) pay a dentist; don't feel like you need to be that person to achieve some arbitrary standard of "homesteader." The "keeping up with Joneses" mentality is alive and well within the broader community (not only Instagram tradwives trying to sell something); reject all of that now, it will not serve you.
On the practical side of things, my biggest piece of advice: learn more about cooking. Even if you're the sole cook in your household and do it for every meal, snack, and special occasion, there's still more to know about food and how to get it from the outside world and into your body in ways that both nourish and please you. Something as seemingly arbitrary as learning to make your own mayonnaise can be life-changing. This is non-gendered advice; everyone should know the basics of feeding themselves by early adulthood, with few exceptions, and that they don't in today's world is nothing short of a tragedy.
