Please help me, t's not too hard?

I think that memories can help us or destroy us- it depends on what you do with them. For the bad memories, you can use themto look back at and learn from so you don't make the same mistakes. If you continue to think about the bad memories, it can drive you crazy. If they are good memories, you can either think about them to lift your spirits up or you can continue to think about them and be stuck in the past while not paying much attention to whats going on in the present. I guess it just depends on how much you think about them.
