Many libraries have the excellent “master teacher series “ or “the teaching company” lectures which tend to be of excellent quality. In my self pursuit of knowledge I have found several specific areas of interest for which I infill my understanding. Architectural engineering (calculating beam loads for instance) and fast Fourier transformations (lots of things) are among my favorites. Pick a specific end goal (like maxwells equations) and study everything necessary up to that. Doing so a few times in different directions (over years) will cover an impressive range of relevant materials. As for how? You must be persistent and playful about it or you won’t follow through.
