Legacy is about being remembered; it's your name attached to tangible achievements, your name credited for effects.

Impact exists with our without legacy. The network effect of your friends' lives may be outwardly invisible, but the impact of their work, on the lives of anyone they lived near and around, had fun near and around, served near and around, worked near our around... is quite vast.

You don't have to be Abe Lincoln or John Rockefeller to have lived a meaningful life.
