I am doing a series called 52-technologies-in-2016 https://github.com/shekhargulati/52-technologies-in-2016 where in I learn a new technology, build a small app, and blog about it every week. I maintain an Evernote where I write down all the interesting topics or projects I find. I go through the list and randomly pick any topic that excites me that day and then work over the weekend to publish something. This helps me keep in continuous learning loop.
