You can learn to code, Ren'py is fairly simple, and there's a plentiful amount of instructive guides on HTML, CSS, C++, Java, and other languages on Youtube and via text.
You just need to put the time and effort into it, but it's worth it - especially with how everything is being digitized and uploaded, it'd be smart for everyone to have a little knowledge with all of this stuff.
Well, there's drawing guides out there. It's definitely not "easy" to improve art skills by any measure (I tried to improve for a bit in HS), but if you're doing it consistently, I've heard that you'll improve with time.
I also imagine that doing different styles, subjects and using different themes can all help you with finding your artistic voice.
The important thing to take away is to stick to something if you're interested in it - ESPECIALLY when it gets hard, as that's the formative part (and arguably the most important) of improving on a skill.
