I think my old self will want my younger self to have had done lots of things I don't want to do now.
Future me can suck it. I'll be selfish in the moment.
This is like watching videos of old folks saying: "I wish I took better care of my teeth". Right, cause thats what matters a lot to you now.
The lesson to be learned is that what you want from life changes. You shouldn't prioritize the needs of a future version of you.
