I don't know who needs to hear this, but your save doesn't have to be "perfect".

So many good points. I was a bit of a micromanager in previous Sims games, but I made a change when I started playing Sims 4. I swore that I would control some aspects, but if "mistakes" happened I would just go with the flow. I am now 42 generations into the family of that first sim and I have come to love (and sometimes cry or get angry with) all the weird twists and turns that happen. I even throw in specific mods to cause extra chaos now and then. Changing the way I play has been great and has made me enjoy this franchise so much more.
