You get to change one very specific, mundane and small aspect of the world to make it better.

I would erase Facebook, Tumblr, Reddit and Twitter, and have people go outdoors for a couple hours every day and interact with the people around them instead of getting all their info from corporate Internet.

Never to have exceeded our place in Nature.

I can only think of big things to change. But I thought of an idea my SIL apparently does: at the end of each day write down three positive things about you or positive things you did that day and then three things you could improve on...in a journal of some sort.

Bring back payphones.

Make is so that on the German keyboard, the Y and the Z are the same as on the English one.

I would make all the food as is bad for you healthy, nutritious and low in calories while it would still taste exactly the same. I'd be able to eat bacon and steak and fried chicken and pastries and cookies as much as I wanted, and safely lose 20 pounds a week.

And I'd make all the idiot antivaxxers and the people at their freedumb convoy protest vanish into thin air. It would be more satisfying for them to all just drop dead, but then there wouldn't be enough room at the morgues. Too bad it will never happen, anyway. The losers are the ones who always end up "winning".

Make it so that pain inflicted on others is also inflicted on oneself, and so that helping others literally creates positive energy. Hopefully that would lead to a friendlier and kinder world.
