One Should Never ForgetI believe that to tell someone to forget about the past is really bad advice. To forget only leads to repeating failed judgements. We shouldn't dwell on the past or live in the past, but we should reflect on it so that past mistakes are not repeated. Even better, be observant with others, see their mistakes and don't make those mistakes in your own life.
I can be overly analytical and get trapped in that complicated web in my head, which is the same as dwelling, so this is a constant struggle of mine. It eventually becomes overwhelming and leads to depression, so I work to keep things in perspective, trying not to live in my head.
I've overcome a lot in my life. There are many issues I've avoided by observing the mistakes of others. Still I've repeated a lot of my own mistakes, but I try to learn from those errors.
For each mistake I learn from, each element I overcome in my past, and each negative emotion I let go of replacing it with a positive one, makes me a stronger person.
