Begin with the end in mind

One of the chapters of Seven Habits of Highly Effective People (Chapter 2, I believe) begins with the author, Steven Covey urging the reader to picture himself at his own funeral. Covey uses this exercise to try and help the reader focus on the important things, with the intention of prioritizing life and making your true values your priority. I fundamentally agree with Covey and completely understand the point of the exercise, but the practicality of thinking of the end, for me, is futile. I wish I knew what was going to happen, or what should happen or what I want to happen. What I have found, though, as I try to visualize "the end" is that it does not exist in realistic terms for me. The funeral home is always fuzzy and it is sunny and the people at the funeral are all people that knew my grandparents, as those are the only people I've ever seen go to funerals.
I think that a more effective way to approach day to day living, for me at least, is to follow my Dad's advice: You know what is right, do it. I think we all spend too much time overthinking everything in life when the actuality of it is very simple. We all know what is right. We all know what we should do. Instead of rationalizing our behavior or making excuses for ourselves on why we should be able to do something that we know is bad, we should all "Do The Right Thing."
