Accept that some of it's going to take time regardless of how fast you want it to happen, because your brain has to rewire itself at its own pace to accommodate new knowledge and methods of processing. And that's OK. Basically, don't QUIT, but be patient with yourself.

Some of the learning will happen subconsciously. As in you'll get consciously stumped, take a nap, or a weekend (or a few years), and it'll magically click at some point. This is necessary, since some of it HAS to be background-processed, again at its own pace. Your brain is its own cloud solution.
