The worst advice I ever received was from my sixth grade teacher. My memory is poor at best, but his guiding words have always stuck in my mind. He said, ‘it’s better to know a little about a lot than a lot about a little.’ It took a while for my eleven-year-old brain to decode the seemingly encrypted message. On early reflection the advice seemed quite sound; diversify your knowledge and you could go anywhere. I focused the next twenty years on expanding my horizons; I was up for absolutely anything. On my thirtieth birthday I realised just how little I’d achieved in my life. Some of my friends had climbed a number of rungs on the corporate ladder, others had achieved in the professional sporting realm, and many had had children and established families. All had achieved by specialising in just one or two areas. I had of course accumulated a range of knowledge well beyond the average human; however, baring the daily crossword puzzle and occasional quiz night the achievement is virtually useless.
