I haven't played the Not So Berry challenge for myself but I have looked through the rules. It seems like each generation has something new to explore so you maybe you could try that. That way you don't get overwhelmed. Or you could choose one pack per generation and explore that fully. For example, with the sims you're playing now you could focus on Get to Work, if you haven't really explored that pack. You could even throw in Outdoor Retreat in the mix for the first generation. Again, assuming you haven't fully explored them.
