The same way we ramp up on anything: by building a system that (actually) needs it. The XYZ (service mesh, provisioning, etc) will fall into place, from there. Or not -- if it isn't really needed.

But in general: learning by building stuff based on a real need -- even if that "need" is just to scratch the itch of some personal project you've always been wanting to do -- has about 10x the staying power (and "interview cred") as what one gets when starting from the mindset of "oh shit, I'm falling behind, I gotta cram on this stuff".

And on top of that: knowing when you really need X or Y, and when you don't -- is often as valuable as, or even more valuable than simply knowing how to do X or Y.
