Really, it is just a matter of knowing what you need to know and remembering those limits. When I fly my VFR Cessna 170B I stay VERY VMC and am familiar with the airspace I fly in, no more. As I have no desire to fly in anything less than 3 miles viz and well clear of clouds in my old C-170 I could fly clear across the country with a sectional chart and not need to know any of that stuff or talk to anyone on the radio. In the Navy, TACAIR anyway, had no need for any of that stuff. In the airlines we are filed IFR every time. At the few non tower airports we may fly into procedures and limitations are laid out very specifically for each and every destination. I only need to read it on the page before me. Having to know that stuff is more of a rite of passage for military student aviators than useful info. You will forget it soon enough.
