“Our busyness can blind us to other people or at least make us feel less guilty for turning the other way and walking past someone who needs help. When we create margin, we give ourselves the opportunity to notice and truly see people. The way we spend the margin we have affects the people being pushed to the margins themselves.” — Terence Lester, I See You
Sometimes, we want to be blind.
