I realized that I have a myriad of interests, and that I put a lot of effort into pursuing and studying them, but ostensibly make very little progress in any of them.

I realized this is mostly due to how I will try to do too much at once, and learn too many things at once, changing which interest I want to pursue daily or hourly etc.

To combat this two months ago I began forcing myself to choose one interest or goal at a time, and only allow myself to use my free time on that particular goal or interest for a minimum of two weeks. So far the results have been excellent, I've made actual significant progress on the goals and interests I've chosen so far. Not only has this been objectively beneficial in the sense that I'm making more progress than I normally do at something, but I find it to be much more satisfying as well, since I can really dig into something for a while before moving on.
