The great British writer Virginia Woolf used to say that she felt lonely in the company of others; what she actually meant is that being around people made her miss the secluded writing spaces where she wrote numerous masterpieces. Woolf was not an antisocial person at all, but she abhorred distractions, and she is hardly alone in this regard.
Some people are able to get into the zone even with distractions all around them. I have to admit I am able to tune out the rest of the world as long as I have a decent pair of headphones on. The only distraction I allow is the music I play, which is invariably instrumental because listening to any lyrics will demand a shift in my focus. By eliminating distractions and sharpening your focus, you can get into a cognitive rhythm that will can deeply augment your learning.
One piece of advice: Remember how I mentioned that a state of flow feels great with one exception? When you enter hyperfocus mode without distractions, you may also enter a state of time distortion called the “deep now.” The efficient progress you are making feels so good that you may forget what time it is, but this can be solved by setting alarms.
