Legacy isn’t loud. It’s the quiet stuff people keep doing because you did it first.

Influence usually travels without attribution. Somebody sees you do something reasonable, adopts it, and within a year it is simply how they operate, with no memory of where it came from. That anonymity is the sign it worked, since an idea only really transfers once it stops being yours.

Do the decent thing visibly and then say nothing about it. The people around you will take whatever is useful to them. Wanting credit is understandable, and it is also the part that slows the whole process down.
