The creator problem. I was just doing a quick thing and oops now it´s a big thing. Trust me you are definitely not the only one that has this problem. Creative work like that just has its way to suck someone in, which can be as good as it can be bad. One of the hardest things to do is, to say: "ok that´s it, I will finish this and then stop for now." I only dabbled in creative works like this a tiny bit, but even just this tiny bit, made me experience this problem just the same. If you are curious, I was trying to write a fantasy book, but doing it properly, with actual world building behind it and all. So, making a world map, history, different races, making a magic system, religion, culture, gods, all the good stuff.
