First of all accept that there is 100x time more useful knowledge to learn than you have time. Next prioritize the things that will be the most relevant to your career or or side projects. Specifically focus on the concrete and relevant over the abstract and esoteric. The most useful topics are going to be applied an relevant to your goals. Think how do I use css over theory of design. It's much easier for your brain to stay focused on items that are immediately relevant. Also focus on marketable projects over knowledge. I took an open source CMS and made the queries 2x as fast is a way better use of time than I red a bunch about Postgres tuning.
