I currently have the short-term luxury to rethink.
I am steering myself away from web dev tools (I'm a Laravel/PHP/Rails/Node.js/Vue/React/GraphQL/DB/server/Perl/HTML/CSS/front-end/back-end/every-bloody-end guy, jack-of-all-trades, master-of-some).
I've been doing it too long and I'm a solo/design agency worker now. I've built some big stuff (and some early semi-famous stuff) and I've also ended up doing the crappy-little-WP-site shuffle.
I am aiming specifically towards tools that reach out a little further.
Basically I am finally, after all these years, properly learning Python, which I have never once actually needed. Because it reaches further than the programming languages on that list. Into desktop app development. Into scientific computing. Into embedded. More towards 3D printing, GIS etc.
And it still works for all the web things, so I can bridge.
And perhaps most importantly, more towards teaching and education, so I can actually be some use before I die.
