What would you do if you had a billion dollars?
After you get done identifying all the things you would buy and have (do this it is part of the exercise). What would you do next? What would you do when you are done having, spending, acquiring?
This is the key to what most moves you.
Really go through the exercise fully or have the conversation with someone (for fun). Enjoy vicariously all the things you would have (get it all) and do. Imagine and experience everything money could do for you.
Once you have bought it all and done it all, what do you want to do then? Start doing that as much as possible.
