David’s Latest Talk

Best- Self Management

What if as a leader, you were able to shorten the time needed to ramp-up every employee, increase the cadence and quality of their contributions, and retain them for much, much longer?

You can. But not by doing “employee performance management”.

In contrast to Performance Management, Best-Self Management proposes that when leaders build cultures and institute practices that support people in being and becoming their Best Selves, then high performance and uncommon loyalty is the natural result.

David debuted his talk on Best-Self Management in late 2018 to a group of 75 successful Silicon Valley venture-backed CEOs at a conference in Monterey. The talk was the highest rated of the day, with 83% of respondents rating it a 10 and 17% rating it a 9. It was also the top rated session in response to the questions “which session was your favorite?” and “which of the following session(s) do you feel will create immediate value for you and your team?”1

Best-Self Management integrates research on concepts such as the Growth Mindset, Strengths-based management, Psychological Safety, and Positive Psychology, to create a truly win/win paradigm of leadership and management. If leaders take this on together, we have the possibility of creating a more inspired, powerful, and purposeful world where everybody wins.

I was inspired by David's talk to create a 'Best Self' culture for my company. We're striving at Engagio to be a place where people want to stay and achieve the best potential, and this talk is full of idea to help make this happen (shifting managers to a 'coaching' mindset, creating psychological safety and self-actualization, etc.)"
