I've never stuck to a schedule. If my Sim has a fight with someone, I may jump to the other household to see how they feel about it. Memories are one of the best things about TS2 to me. I can keep up with almost everything by just checking the Sim's memory panel. Example: I may forget one of my Sim's had a crush on someone, and wondering why they keep having a heart thought icon about a Sim I haven't seen in the game for awhile. Looking at their memory panel can remind me, oh, yeah, they met them and they hang out a few weeks ago....and they now want to remind me they like them and want to be with them again. TS2 has so many little things that jog our own memory it's the deepest game in my opinion. I may not remember why Goopy was fighting Benjamin, but if I make them playable I can find out. I may forget I made one of my Sims argue or toss a drink on someone, and weeks later that other Sim is still angry with my Sim or is rude to him or her. Checking the memories can sometimes tell me what I forgot. I have never kept notes. I didn't need to do much of that because of the memory system.
