The wrong lessons

I thought leading meant having the answers. It doesn't. It means making sure the team has the context, the tools, and the safety to find answers faster than you could alone.

The numbers

12 engineers across Wendy's, Takeda, Stellantis, Sifera
Team productivity up 25% through mentoring
Sprint delivery 86% → 94% after taking over at FortressOS

The real lesson

Mentoring compounds. Every hour spent teaching someone to fish paid back in weeks I didn't spend debugging their fishing nets.
