How to not Regret

Dear Aditi,
   I have a lot of friends who are in a lot of different fandoms. Some of them are in the same fandom as me. Some aren't. I want to tell you about the ones who aren't.
First off, everyone has the fandom superiority complex. In which they think their fandom is better than anything else. I have it. You have it and everyone I know has it. But when I am not in a fandom, or I was in one and now it's sort of dulled down. I look at these people and think, 'damn they are going to regret their choice soon enough.'
I don't think I have any right to think that. Because it's their life. They can do what they like with it, whether they will regret it or not. I, personally, have never regretted any of the fandoms I have been in. Harry Potter, Percy Jackson, Hunger Games- grat. All the bloody anime I have watched- pretty good. All the manga I have read-  very good. Once Upon a Time- beautiful. Dan and Phil- well I am trash right now, so I don't know. But it made me wonder, will I ever regret it 5 years from now, maybe 10. I don't know. I don't want to. But I might.
I think it does make me grateful that I never got into Justin Bieber or One Direction, because I would regret fangirling over Larry. I assume it's Larry that people fangirl about. I don't have first hand experience.
Je Ne Regrette Rien.
Upa.
