Build something that keeps running after you leave. That’s the real flex.

Anything that needs you present to work is a job, not a legacy. What lasts is built so other people can run it: a system someone else can follow, a skill you taught, a group that keeps meeting without you calling it. Building that way means giving up the quiet satisfaction of being indispensable.

Look at one thing you are currently the only person who can do. Write down how it works, or teach it to someone this month, even badly. Being replaceable in that one spot is what frees you to build the next thing.
