Ok. 

OK. 

Now as a rule, I normally say something along the lines of: "Let the past be the past and leave it at that." Would I really want to change anything about my past? Surely it has some significance?

Personally I don't think I'd go back to my past and change anything. I believe, mostly, that everything that has previously happened to me has somehow helped me understand things. Or has shaped me into the person I am today. 

I won't go into specifics here as that's a little too personal, but I'm pretty certain some events from my past has led me to have the outlook I have now. Things have happened to me that have led me to see certain things in certain ways and believe all sorts of mantras and stuff. 

Although on the other hand I'd certainly go back and change some of those EMBARASSING fashion choices I made as a child. God damn. What was I thinking. HOW did I or my mother think they were good ideas.

So in short, don't change the past, it made you who you are today. 

Peace out.
