Force Multiplier Is A Mindset
- Being a force multiplier is a mindset, not a title.
- It means taking an executive's vision and ensuring it is communicated, organized, delegated, and executed across the organization.
Role Overlap In Small Companies
- In small companies the EA and chief of staff roles often overlap because there's no one else to fill gaps.
- If you hire one but not the other, that person will cover both EA and CoS duties until scale demands separation.
Let Go When You Move From EA To Chief Of Staff
- If an EA moves into chief of staff, avoid becoming the bottleneck by intentionally enabling the new EA.
- Reassign responsibilities, coach the new hire, and let the EA build direct context with the principal.

Multipliers
How the Best Leaders Make Everyone Smarter
Liz Wiseman
In 'Multipliers,' Liz Wiseman explores the differences between two types of leaders: Multipliers and Diminishers.
Multipliers are leaders who bring out the best in their teams, amplifying their intelligence and capabilities, while Diminishers are those who stifle their teams' potential.
The book outlines five disciplines of Multipliers: Talent Magnet, Liberator, Challenger, Debate Maker, and Investor.
These disciplines help leaders create an environment where team members feel valued, inspired, and empowered to contribute their best.
Wiseman's research shows that Multipliers get twice as much from their people compared to Diminishers, who often leave their teams underutilized and demotivated.
