I would give you different advice than "just start building projects": The language and framework that the first iteration of something is built in does not matter. You already know enough tools to build anything you want. If you want to build stuff, stop learning new tools. Maybe you'll replace the time you've been spending learning new tools with video games or TV shows, but maybe you'll replace it with building stuff, instead.

This is a classic trap that young programmers fall into, to fetishize tools and condition doing useful work on learning a bunch of tools. Just say no!

(This isn't anti-intellectualism - you'll eventually learn a bunch more tools as you go.)
