Making & keeping promises.
That's what entrepreneurship and creative work come down to, doesn't it: Can we make and keep promises?
Promises to our clients, for sure, but more importantly, promises to ourselves.
Because in most cases, no one's watching and no one knows what we are working on, and when it's due.
But, we do.
So, unless we build the skill of making and keeping promises to ourselves and shipping them before they are due, we will find it very hard to show up as professionals.
