From an "aged" polymath -- as one ages (I am a ripe old 52) the problems of polymathy grow if one has not "settled" (and I mean that literally and figuratively) into a career with some "legs". With a degree in communications I moved from teaching, to Human Resources, back to Training, and finally into sales to support a growing family. Now I must decide whether to continue throughout the rest of my working career to be in sales or to approach something more fulfilling. Not having stuck to "just one thing" I am at a disadvantage as I approach the second half of my life. It also tends to poke at my anxiety -- I hope not to spend my "golden years" saying "welcom to Walmart".
