Lately, I've thought about this myself.

Like what would my 21 year old self say if someone said, "At age 51 you will be learning a sport that hasn't been invented yet (Wingfoiling), you will be divorced with two kids. You will have been a teacher, a remodel contractor, a home inspector, you wil write two books and write on a futuristic platfrom called Medium. You will still be enjoying cannabis occasionally, and on Halloween weekend in 2024, you will be wearing a pink wig with shades, micro-dosing on mushrooms, dancing with your 45 year old girlfriend who is wearing a fairy costume!"

My 21 year old self would probably say, "Fuck yeah! That's rad! Want a hit of this joint?"
