Simple enough, you have to collect every single collectable. But you also have to max out every single skill and your job. The catch is, you don't start with any money at the beginning.

Goals of challenge:
-Collect all the collectable
-Max out all skills
-Max your job performance
-Have at least 100,000 simoleons
-Get married
-Raise up 4 (or more!) children to YA
-Live happily, ever after. The End.

Rules

1. No cheating AT ALL!
2. When you pick a lot choose the biggest empty lot, and all you can get is a bed (or sleeping bag)
3. Sim must be YA

That is pretty much it, all you do is have an awesome life before your sim dies.
