Has anybody found success with coding? How easy / hard is it to get into?

Nope. I spent a lot of time at the beginning of the learn to code boom back in the 2010s on it and even attended an RL bootcamp in a non-reclusive period back then. You can take the following with a grain of salt as I'm sure the people who became successful at freelancing or became remote programmers can chime in more later.

IMO, it really depends on your cognitive ability especially in terms of logical problem-solving whether you'll be a good coder or not. Anyone can learn some syntax. I wasn't very good algorithmic thinking or structuring applications and I had devoted a lot of time with not much to show for it, but I am an extreme case and probably have a learning disability. What will seem easy to one person is hard for another and it's often said by programmers that not everyone is cut out for it.

I think it might be a good idea for you to check out the webdev or freelancing subreddits to get a better idea of expectations. The difficulty of making it work depends on what your needs are and what level you can attain skill-wise. Web Dev is what I assume you're going for since it has the lowest barrier to entry. There are courses on udemy and there's stuff like freecodecamp but the latter handholds you a lot so you'd have to learn how to set things up on your own. You'll have to learn the technologies in demand after you learn the basics of coding and then make your own stuff as in web apps and have a portfolio website and such so you can show people what you're capable of making.

I imagine you're going for like freelancing and getting paid per project since obtaining a legit full time remote job with no experience isn't very realistic unless you're super amazing. I knew a guy who dropped out of CS but he was making some node.js packages on his own and he got hired by a start-up. It wasn't remote especially since this is going back some years, but just highlighting the level of prowess for that type of scenario.

It's important where you live as you can live off of smaller assignments more easily if you're not in a high cost country.
