Write Your Eulogy
One of my favorite songs is Live Like You Were Dying by Tim McGraw. You can click here for the lyrics. It helps me clarify my lineup when I'm trying to juggle elephants (yes, I still try from time to time).
It might be morbid but why not begin with the ultimate end in mind and write your own eulogy. What do you want to be remembered for? What do you want said and written about you? What accomplishments do you want to have achieved? Lay it out in detail. Review it on a regular basis and don't be afraid to edit, delete and add to it.
