You actually described your problem: "constantly changing subjects". Stop it!

Deep work is not the goal, an obsessive interest in a single subject leads to deep work ethic. When you are truly intrigued and/or passionate about something then deep work follows. Not the other way around.

One clue to finding your niche is to notice what you get very angry over and want to do something about it. Having found that is the beginning of finding the "juice" and the rest follows.

As an extension to your comment, here's a decent advice which is based on the principle of DeepWork.

So basically, instead of just going through different subjects try to work on 1 subject/topic for 30 hours (across multiple days, maybe take a break between days) and then check if you want to go further on the subject. Apparently, 30 hours is a good enough time frame to realise if you have an interest on the subject of your choosing.

I'm struggling to actually start with something interesting, and after reading your comment I remembered the process outlined in the article. Thanks!!
