Yes, the literature part was because this is the only major that benefits Adventurer career (the one which title is Space Pirate on the top level).
But yeah, I usually don't bother completing lifetime want as its two major benefits are a lot of influence points and aspiration points (which I can easily save up) and permanent platinum.
But...
Permanent platinum can be obtained two other ways:
1. By filling up the lifetime aspiration bar to the max. This is the bar that gives aspiration benefit points (which can be used to get a secondary aspiration). It slowly raises or lowers depending on sim's aspiration bar. Not only that, but some major life events like marriage, graduation, opening a business etc will raise this meter some amount when they first occur.
2. If your sim gets a genie lamp (which can be delivered when a sim has a high lifetime aspiration bar and high hobby enthusiasm), they can wish for peace of mind, which will give them permanent platinum if it succeeds (if it fails, enjoy everything breaking!).
So yeah, have your sims enjoy their hobbies at their free time and good things will come to them eventually. Including less of those "Have a Baby" wants.
