This process has taught me a lot about myself and about life - mindset, discipline, ambition, maintaining a good attitude, avoiding burnout (physical and mental), exercise physiology, how to coach and be coachable, be a supportive teammate, and how to sustainably pursue a ~10-year goal. I do think this journey comes at a time and energy cost to pursue tech things (side projects, new langs/tools/frameworks) but at the same time, I think the lessons from pursuing anything really ambitious cross-pollinates to other areas including career.
Would be interested to hear of any other stories of people pursuing other hobbies at a somewhat high level while simultaneously pursuing career ambitions! Thanks for the post.
