This reminds me of the Tim Ferriss interview with Derek Sivers were everyday Sivers pushed himself to bike fast and then one day he said fuck it and decided to enjoy it. Later he was shocked it only took 2 minutes longer. Where is your balance of pushing yourself while not putting everything else on hold? From my personal experience I enjoyed the journey of reaching my own goal of 5k in a year when I found the balance that worked for me and was sustainable. Great post as always Maarten van Doorn — you’re a hellavu thinker.
