"I" as in me, you, us, the person who's on the line. This is the work of a human. The audience can make a direct connection between you and the thing you're offering.
"Made" because it took effort, originality and skill.
"This" is not a wishy-washy concept. It's concrete and finite. It didn't used to exist, and now it does.
and, "Here," because the idea is a gift, a connection transferred from person to person.
These four words carry generosity, intent, risk and intimacy with them.
The more we say them, and mean them, and deliver on them, the more art and connection we create.
