I honestly find coursera and edx are by far the best use of my time too. Structured learning with a beginning, an end and a few individuals (professors) that specialize in a field. I'm doing things that ARE actually in my field (similar to yours) but set me apart completely at work where most people don't take the time to do any sort of learning and just focus on the daily grind. As a side note, the other more fun yet still kinda learning use of my time has been to watch a few older Japanese shows - not the crazy all-over-the-place stuff they have today. For example, Musashi (2003). It's fun to watch and at the end of every episode they talk about a site in Japan where Musashi traveled in real life. I find this type of show enriching. Another good one is a show called Change (from 2008) which is again Japanese about a young man randomly becoming prime minister of Japan. The show again discusses the intricacies of Japanese politics in a funny way but with a big dose of the real issues in Japan (e.g., the small number of young people vs the old).
