Donald miller's new book is about the idea of a eulogy. What legacy are you going to leave? And he has a couple of exercise questions in each one of these chapters. In seven, you have to identify that i will likely pass away when i am about x years old. If i die when i am x years old, that means i only have y years left to live. It creates momentum, or the motivation, to take action now and start creating the life that you you want to live.
