ADHD

Hi. I wonder how do you keep following through on your ideas/goals/topics that you want to research (in specific field or some niche idea/interest) and not burn out/get bored and forget about them altogether?

I've found I often don't have enough time to spend on an interest right away, and then I put it in my todo list/special folder in obsidian to check on later (article, wikipedia page, a video, movie or a book), and then it just sits there. When I open the list I start to think that I need to fix this pile of stocks and start going one by one on them, but by that time they are no longer an interest to me.

Say I got interested in researching history of WWII and Nazi regime because I watched a movie/read a book about that. Then, I just go on to the internet to find out more about it. At the moment I'm thinking "I dont have enough time for all that", so I just get some books, articles, videos about it and stuck it in a file named "to research". Later on, I'm terrified of even looking at that file, it seems large, and when I open it, I'm bored from second one because I "forced" myself to do this, instead of flowing inside of it, like I did with the movie.

I guess being dilligent is very hard for me. I feel like the problem mainly lies in my "fear of time" more than a spurred attention span. But I'm thinking about how can I keep up with irl things like work/chores/whatever while tagging myself with hobbies instead of being either too chaotic or too "formal" without any interest left behind? How do you do that?
