Make sure your traits make sense and are realistic, for example I gave my first daughter her first trait which was self-assured, which means she tends to be more confident and well, self-assured, then when she aged up, I wanted to give her a semi bad trait so that I'm not just giving out good traits, I want to balance it out a bit. So, I (without thinking it through gave her the erratic trait, which used to be called insane trait). Well, these two traits don't make sense together because an erratic individual is unlikely to feel confident, except on occasion and probably for some insane delusional reason. I felt annoyed by this sim's trait set up, to the point that I was eager to have enough points to buy the re traiting potion. I ended up giving her the vegetarian trait, which is somewhat bad. It fit her personality and playstyle because she likes to meditate and is interested in wellness so naturally being a vegetarian fits with that. I don't really have a lot on my mind to say about this question. or Insight for you, I just looked at a guide that describes all the traits in the sims 4 and gives a brief description of how they work, and what there good for maybe you could get use out of that. It's under ultimatesimsguides traits. Search for something like that.
