I always have fun doing this ....
Create a Sim with the collector aspiration or any nature aspiration or Friend of the World. Give traits like loves outdoors, outgoing and dance machine. If you choose the active trait your Sim will be able to "jog here" after level 2 fitness, I think. Handy for moving from one collection site to another.
Move Sim onto a big lot. You will need the space. Cheat money to zero. Your Sims now has the ability to disco nap if you choose the dance machine trait. Use public or neighborhood restrooms, shower at the gym and nap on benches. Sims eats what is harvested. Sell collected items to buy meals until plants can be harvested. You Sim will not require as much time to sleep because of trait.
Travel and meet other Sims collecting as you go. Pray that your Sim is not abducted by aliens. A baby not needed at this point but welcomed if it happens. Work on the Nature aspirations and Friend of the World aspiration simultaneously by switching back and forth. Athletic aspiration requires Sim to workout at gym. Snag that one when a shower is needed. If you have Jungle Adventures there are two aspirations that require collecting and travel. Sell, sell and sell more. Buy skill items. Start a tiny home with 4 tiles and start skilling when Sim is home. Sim will learn faster and plants do better.
The point of all this...
It takes 5000 aspiration points to get a money tree. Get a money tree. Wait for money tree to seed. Put money tree in household inventory to get more seeds. Plant new seeds and put the original money tree back. Your Sim is set for life. Play the rest of the game as a stay at home parent or do an aspiration you haven't tried. With money your Sim can head off to college or do anything because your Sim is rich. Expand to the fortune aspirations and end up in a mansion.
Short version ... cheat the money seed and ruin all the fun!
