My sim usually fulfills several at s time eg. A career type one, a family / relationship one and then .maybe a pack walkthrough one. Just like in reallife where I have a mix of shorter and more long term goals. I like to have short ones so I can buy some of the useful reward potions and long ones to guide my storytelling etc.
Packs should come with 2 or 3 aspirations short walkthrough ones to learn the pack, medium ones to earn rewards and a lifetime length one.
I love being sble to swap aspirations out at any time and not losing progress if I return to them (just as you sometimes do in real life) and i hope future games allow this.
