Draw a timeline of your life from now to the grave, then divide it into intervals of five or ten years. Each of those intervals—say, from age 30 to 40, or from 70 to 75—is a time bucket, which is just a random grouping of years. Then think about what key experiences—activities or events—you definitely want to have during your lifetime. We all have dreams in life, but I have found that it’s extremely helpful to actually write them all down in a list.
