"High-intensity without asking for what you want leads to burnout -- sustainability requires honest communication"

Executive Coach (ex-Slack)
The people pleaser who keeps everyone happy in the short term but erodes their own fulfillment over years
Berger's own transition from Slack PM to coach -- modeling the practice of asking for what he actually wanted from his career
Kenneth Berger was the first product manager at Slack and spent over 10 years as a founder and operator before transitioning into executive coaching, where he has spent seven-plus years helping startup leaders navigate the exact tension between ambition and sustainability. Their core argument: Burnout comes from misalignment, not intensity. People burn out when they suppress what they actually want to maintain a high-performer image.
The evidence is specific: Berger's own transition from Slack PM to coach -- modeling the practice of asking for what he actually wanted from his career. Furthermore, the 'dream behind the complaint' technique: mine complaints for implied visions, then check if the dream is genuinely inspiring or embarrassingly unrealistic. The people pleaser who keeps everyone happy in the short term but erodes their own fulfillment over years.
In Kenneth Berger's own words: "For me, the impact was about making this work sustainable so that we're not burning out or selling out, but actually able to pursue these hard goals that we have in startups." (Framing the false binary between burnout and selling out.)
