Make peace with my past?

I put "7 Rules of Life" in the previous article, because I thought it said good things and I would try to follow those.

However, I'm not sure what it means to make peace with my past. I wonder if it means that you forgive your past mistakes, or that forgive someone who did something bad to you, or...

I don't know who wrote this "7 Rules of Life" so I have no idea where I should refer to.
So I've decided to interpret it as meaning that I should be positive about my past!
