Yeah, I've been pondering that as well for a while. The biggest boost in learning I've had is:

* Doing a small side-project that you follow through on. Just doing a little bit each day. I've done PHP (Laravel / Symfony) and JavaScript (jQuery, now mostly Vue.js) for most of my "career". Now I'm doing side-projects in Python (I try to use Flask or Django). Actually, I'm just writing up an article on how I want to focus on "boring" tech, because I don't want to learn a new technology on the side that gets obsolete 2 years later (I'm looking at you, AngularJS 1 & bower & grunt & gulp).

* Get on board with a team where many of them are senior developers. I've been in projects where I was silo-ed off and worked on a specific feature - Boost Level 4 / 10 (because I get to dig deeper into specific areas, if I so choose). In projects where I was the most senior developer because the company focused on only hiring junior developers and doing scrum / agile - Boost Level 3 / 10 (we were discussing so much, so actual development time was little). Team of senior developers each with their specific skill set working on an MVP deliverable within 2 months and you only know 60% of the technologies used - Boost Level 8 / 10.
