The best managing director I used to work with had a simple rule: 'If you're not sure whether to escalate something to me, escalate it.' He explained that he'd rather spend 5 minutes telling me not to worry about something than find out about a real issue too late. This simple rule created psychological safety and helped me grow faster.
Netflix Leadership Transition
Netflix lost 1M subs from April-July 2022. Reed Hastings stepped down as CEO in January 2023. The stock is up 140% since then. Sometimes the best thing a founder can do is let go. The second best thing is to know when.
My Biggest Consulting Regret
I spent 5 years in Big 3 consulting. My biggest regret was not taking more notes. The amount of learning that happens in consulting is insane. Every partner conversation, every client meeting, every internal discussion is a masterclass. I wish I had documented more.
