A way to enter a name for person 1 and person 2 on any given day. Have a list display in the dashboard of who has been a Person in the last 30 days. This makes it easy to ensure you're spreading the gratitude and appreciation around well. One might expect to see 22 people outside of their immediate family in a 30 day period in the list (4 weeks * 2 for partner/posterity, figuring they would be person1/2 at least once a week, means 8 times the names would be the immediate family) and they also know that the next people they need to appreciate are people who are not on the list.
Alternatively, a list to track who in your life should receive gratitude and appreciation, similar to the hot list - possibilities - and then the daily person 1/2 becomes like the hit list. Maybe people come back to life from the achieved list after a period of time to make sure it's not just a one and done thing.
