"Let Go of Your To-do Lists"

And let go of your long to-do lists and goal lists. They are a futile attempt to keep from missing out. You will miss out, but in striving to do everything, you’ll miss out on the wonder of the thing you are doing right now. What you’re doing right now is all that matters. Let the rest go, and enjoy the fish you’ve already caught.
