You might be INTP. FInd out and if you are, find a community of them. It helped me.
And to put it succinctly, minimize your information firehoses and reject the notion that you need to keep abreast of everything even if it is not relevant to you.
Purge all of your reading lists and resist building them. If you keep any lists or bookmarks, require that they be things you HAVE read and want to keep as reference for later. I do have a "toread" bookmark folder, but I almost never go back to read things there.
Visit only one or two tech sites a day. For example, I come to HN to the exclusion of almost anything else because it does a good job of showing only relevant things. But I limit this to 3-5 times a week and only when I'm bored. It's a good filter.
Lastly, get a personal project that serves as a good source of challenges. Use it to help decide if you should read about a particular technical topic. You'll find that this serves as a good filter, but at the same time you'll magically seem to read about things relevant to your technical challenges in a surprisingly timely manner.
HTH,
