What should I do with my save I've had since I was 6? (2014)

At first I didn't wanna touch with it and make a new save but oh frick no I guess so im back playing the old one

Thing is I don't wanna tamper with it too much cuz it's one is the oldest parts of my gaming history of that mak sense. I have 33 miis, (me, 13 family members/relatives, 2 kids i made friends with one day and never met again, 2 babysitters,3 youtubers, 9 old friends, mario and my school crush when i was 8) should I add more? I wanna try to buy everything but idk if I'll have the determination. I was thinking of trying to get me and my old school crush in a relationship (but I also feel like that's kinda weird cuz we were like 8 when I made her mii and we're 17 now and don't even know each other anymore) if I decide to add ppl? Who should I add? I don't wanna do people that became famous after 2014 cuz I feel like it ruins the time period. Anyway very long paragraph plz give me suggestions

Love you guys
