Best way to move from web/network pentesting into low-level bug hunting? (ADHD, keep losing steam)

I work as a pentester, so my day-to-day is network and appsec. On the side I've been trying to learn ARM assembly because eventually I want to hunt on low-level targets — Android kernel, browsers, that kind of thing.

Some context on where I'm at:

I have bug bounty experience and I reverse engineer regularly

The closest I've gotten to C is reading native libraries in Android apps, but the attack surface there is tiny

So most of my "learning" is reading ARM and C snippets in isolation, with no target to apply them to

That's the problem. Studying without hunting kills my interest fast. But I don't want to jump straight into hunting and discover I don't know enough to get anywhere.

So: what's the better path here — and specifically, what works if you have ADHD and can't sustain pure theory?
