Yeah, some pretty crappy things happened to you. And yeah, some people treated you pretty badly, and never did pay for it. And here’s the thing – that was then and this is now. It is not your job to make others pay for being less than you think they should be. It is your job to continue on, being the best you that you can be; making mistakes and cleaning them up to the best of your ability; learning the lessons that you are yours to learn. The past is the past. It is over and done. Having regrets about it just keeps you living in the past, when where you want to be is in the present. Learn your lessons and move on.
