As a newbie I, too, ran into those problem areas where it was difficult for me to manoeuvre the blade, thus leaving pesky, minute stubble behind. My advice: don't sweat it. As you progress you will learn what works for your face and beard and what doesn't. Your best tools are a professionally honed razor and, most importantly, a lot of patience. The rest you will acquire over time. Hang in there and enjoy the ride!
