Helo guys, I feel like my sims is filled with trashy or repeatable memories, so I was thinking to get it stopped using mods, does anyone have a clue on finding one or create one?

So you want BoilingOil's No Trash Memories, I think. But if that mod is too big for you, it should be pretty easy to make your own. Not sure if anyone else has done it before, but you would clone the memories you want to change and then edit them to make the repeatable or unique. There should be two memories each, though--one for self, i.e. the sim gets a memory of being an overachiever or graduating, and then another for family, i.e. memories of their family members reaching the milestones.

You can use DiLight’s How to Create Your Own Custom Memories Tutorial for instructions but instead of working from the tutorial package, you will clone the memory you want to edit in SimPE’s Object Workshop. (When you clone, you can uncheck all boxes. Memories are located under Other.) Then extract the bhav “0x00001002(4098) CT – Add Memory” from the memory and make your edits to your copy.
