Expertise Does Not Have Units

From [Expertise Does Not Have Units](http://bettermess.com/expertise-does-not-have-units/):


Sometimes, the problem with achieving a goal set for you by a ten-year-old is that you have no idea what to do at the finish line. The world changed and I missed it. I was an expert and I was tired and bored. For me, the sweet spot of expertise hovered around the 70% mark. Being an expert is boring. While there’s always more to learn and new problems to solve, nothing is so thrilling as problems that make me fail. The moments when I struggled the most were the moments when I was scientist. I was at my best when comprehension was just out of reach.
 
Expertise is a funny thing. There’s no way to measure our progress towards obtaining it, yet we always feel far from our goal. When I did finally feel like an expert it hardly felt valuable enough to hold on to. I only learned afterward that expertise is not a destination but a vehicle. It’s the golden ring that makes us jump higher and reach further. In the end, it’s just a ring.
 
I can’t blame that little boy though. How could he know that he was already a scientist?
