What I may do-
Present people with lots of brooms and mops, to clean up the surroundings. We have a long way to go.
Teach world leaders to stop being in office forever.. too many seem to be unretiring, and unrepentant about it.
Ditto for cricketers who have outlived their usefulness.. Gavaskar had once said, "It's better to go when people are asking Why, instead of waiting till they say Why Not?"
Teach screenwriting and editing to as many filmy types as possible. Brevity is the soul of wit, but a lot of witless directors don't understand it.
Ask people to exchange gifts themselves, so I can retire.
