I also love Factorio - it gets better when you play multiplayer and with mods. I've found, getting back into it, that Project Euler really helps me 'just start coding'. Last time I got into it (around 2014) I would focus on trying to understand the mathematics and solving things by hand. Now I look at a problem or two every few days, and have fairly streamlined solving them. Breaking the problem into chunks, making sure those chunks work with tests, gluing the chunks together to get the fact needed by the question, running with the specific input needed for the answer, realising the naive way I implemented the solution is way too slow, adding timing information, analysing the algorithmic complexity, reading pages and pages of mathematical theory... Sometimes it goes off the deep end, but getting some result almost immediately is so useful. It's the reason Factorio is fun (you can just build it by hand, most of the time) and Excel is used everywhere (you can see the algorithm and its results together, as you build it). It takes a bit of discipline to do yourself, when the gratification loop isn't built in to the tools you're using, and that's why I think Project Euler is so useful. You get short, achievable programming problems that you can solve quickly and build a habit of solving efficiently.
