Since then I’ve come to believe you don’t always have to use things you love, and it’s not always so practical to be so practical. Now that I’ve grown up, I realize that all that delicious dilettantism pays its way as much as any degree in medicine or engineering, by making me remember every day—whenever I pick up a book or watch the Science Channel or try to read a map of Asia for no particular reason—that life is amazing and there is no end to the wonder of it.
