Step by step on how to get the best lifestyle in Sims 4 1. Make a female young adult Sim with the "looking for soulmate" trait mixed with evil, self assured, and genius (make her look like a hooker too, that helps) 2. Find a married guy or girl (only guy would work in this situation really) and have an affair with him. 3. Convince him to leave his spouse and move in with you. You control him now. 4. Get pregnant. Simple as that. 5. Get married to your new boyfriend. 6. Have the baby, then divorce him. Pay barely any attention to the kid at all also. 7. Make her stay up all night and do nothing. Trust me, she needs to be low in everything for the next step. 8. Drown her. Making her health low makes it faster. 9. And you're done. You now control a single dad who left his perfectly good marriage and life for a life with a kid he didn't even want and a dead wife. The rest is up to you, but I suggest making either him or his kid gay. That adds to the drama of the story.
