A couple of months ago my friend Femke, a product designer at Uber, started sharing her journey of becoming a runner. As someone who’s been running for years, I found it fascinating to watch her quick progress. Looking at her back and forth progress during the past few weeks has reminded me of the process we go through in our careers. We look at the tools we use and believe they are what will make us cross the finish line (it’s not) just as buying a new pair of sneakers doesn’t make you a world class runner.
