I suspect I have spent just about exactly as much time actually writing as the average person my age has spent watching television, and that, as much as anything, may be the real secret here.
(William Gibson, 2002)
I like this, not for the particular criticism of television as a time-sink (for there are plenty of others) but for the notion that even relatively middling (but a fortiori also the large) differences in how you spend your time, across the months and years of your life, makes you into the person you are.
