I tend to be too serious, so here’s my effort at “light”!
Some people have a “Bucket List”. I have an “If I Had a Magic Wand” list. Here are the sorts of things I would arrange in the world, the way I feel today, if I did have such an instrument:
Everyone on earth would have a home, and all their basic needs filled.
Of course I would save the environment.
I wouldn’t make everyone happy, because I believe, as Fritz Perls said, “You have to suffer to grow”, and I believe in personal growth (and maybe happiness or contentment later).
I would cure cancer and other awful diseases. They interfere with life and love and personal growth.
I would eliminate bugs that sting.
I would grow trees everywhere, and teach every generation to treasure them.
How’s that for a day’s work?
