This is the point I came to with German and was at a level where I could start speaking it (poorly but enough to be understood) all the time with native speakers. I read up on some things from time to time but mostly ignore a lot of the theory as a child would and just refuse to switch to English as much as possible. It's probably slower this way but it's been one of the few ways I've actually been able to be consistent with practice.
