"You never know when a typical life will be anything but, and you won’t know if you are rewriting history, or rewriting the future until the writing is complete."
This quote is from Debbie Millman in her book Look Both Ways: Illustrated Essays on the Intersection of Life and Design.
It's a good reminder that to make a decision, to make a start, to get going.
You won't know what the impact is or what transpired until the work is complete.
However, without the start, you'll never know when a typical life will be anything but.
