What is the best trait combination if you want to complete all collections in the game?

My Collector Sims start with a Nature aspiration like The Curator or Freelance Botanist so they get the bonus Collector trait. The personality traits I use for most of my Young Adults are Music Lover, Genius, and Ambitious. I've used this combination with many Sims, including Vlad, Brant, Caleb, and Salim, who have completed a lot of collections as well as aspirations and careers in various games.

Teens living on their own start with The Curator aspiration. They always start a small garden which unlocks the Freelance Botanist aspiration. Personality traits for teens are Music Lover and Loves Outdoors both of which keep them pretty happy in spite of starting out with nothing, including power if they're living off-the-grid.
