for me, i always try to read about something new every day. I also try to visit technical sites (such as HN, StackOverFlow, ExpertsExchange etc) and read through different discussions, whether it's a specific programming obstacle someone is working through, or find different discussions to browse through. One final activity I partake in is signing up for different curation lists (such as Hacker News), I find these help stay up to date on different technologies.
To sum it up, never stop trying to consume information, not only does it keep you up to date, but it will benefit you in the long run when learning new concepts.
