I've been given the opportunity to take a few days to a week to learn something new/focus on a project that would further my professional development. As an interaction designer, I could go so many different ways— visual design, prototyping, etc. but I'm not sure exactly what. A bit overwhelmed by the choice, I can't quite make one. So....help? I'm looking for something that could serve as a decent springboard within a few days, but provide further learning opportunities down the line. I have good front-end development knowledge, but badly need to catch up on recent trends. I was thinking of learning an animation framework, or perhaps digging deep into FramerJS? Or what about something like Yeoman or Node?
Any help or direction into what is most useful these days (for interaction designers/designers in general) would be appreciated. How do you decide what to learn, and balance fun with practicality/work usefulnesS?
