The hardest adjustment I made as a leader was learning to not be the smartest person in the room.
I came up as an engineer. For most of my career, being valuable meant having the answer. Knowing the technology better than anyone else. Being the person others came to when they were stuck.
That instinct served me well until it started working against me.
Supplying the answer made the team weaker
The first time I led a team of strong engineers, I kept doing what made me successful as an individual contributor. I jumped in with the answer. I solved the hard problem in the meeting. I proved, again and again, that I still had it.
And I slowly realized I was making my team weaker.
Every time I jumped in with the solution, I took away someone else's chance to find it. Every time I was the smartest person in the room, I confirmed that the room needed me to be. I was building a team that depended on me instead of a team that could outgrow me.
Ask instead of answer
The shift was learning to sit on my hands. To ask a question instead of giving an answer. To let someone struggle through a problem I could have solved in two minutes, because the struggle was how they would grow.
It felt like doing less. It was actually the harder job.
It took me years to stop measuring my value by what I personally solved and start measuring it by what my team could solve without me.
The goal is not to be needed. The goal is to build something that does not need you.
That is not a downgrade from being the expert. It is the next thing after it.
