This is how I'd start the day:

I'd ensure that every person on this planet was able to get up and get out of bed just as the sun starts rising, and I'd make each person go to their window and I'd have them watch the sun rise and I'd instill in them the hope that this day, of all days, will be the best day ever.

I'd ensure that they not get distracted by the neighbor's baby crying or by the condition of their surroundings or by their fear of defeat or their need for retaliation. Instead, I'd make them all feel grateful to be alive and awake and moving, and I'd make them all smile despite themselves.

I'd ensure that enough food and money was in their wallet for this day - but no more than enough - so that each and every person was on the same footing, and yet all their cups would be full.

This is how I'd spend the day:

I'd ensure that people would think outside of their own boxes, think long-term, and long distance. They would wish for global peace and the end of starvation and ignorance. Not because someone urged them to, but because they really felt it was time to think about others, as well as our planet.

I'd ensure that no news would need to be written except for good news about people doing good things. There would be hour-long documentaries and pages upon pages written about "Life": A woman who works full time as an accountant yet spends her weekends tutoring children. A man who works as a butcher yet takes in stray dogs and cats. A city dweller who's found a way to grow vegetables on his 4x5 balcony. These people would be highlighted in the news not for being extraordinary, but for being ordinary, and they would be the only new news of the day.

This is how I'd end the day:

I'd ensure that everyone would go home after a productive day to a peaceful place, a safe haven, either alone or with their loved ones and family, feeling fulfilled and yet not tired. Feeling ready for another day just like this one.

I'd ensure that every person on earth had a safe and comfortable place to lay themselves down, where they could just close their eyes and smile about the day they'd just had, and dream about and plan for the day yet to come.

I'd ensure that not one of them would care to be, nor want to be, nor need to be Ruler For A Day.
