Would you actually change the moments in your past?

No. They have made me the person that I am today.

Not in the least.
It is all the Nature's flow which I'd not intend to even wish to disturb with any kind of Kalpvruksh (tree that fulfills man's all needs) or magic lantern or Kaamdhenu (sacred cow which is said to grant all wishes).

Maybe small things, like if I upset someone or something.

Just certain ones. Nothing horribly major though.

A few.

No

Yeah. I wish I had stopped being fake far long ago.

Some things, if I knew then what I do now.

I guess you can do amazing things with the brain

Only the moments of introspection

I can think of a few.

I would if I could

A few.
