What do you do when your Sim(s) are stinking rich?

I have the same problem i'm doing a rags to riches and for fun i bought a lottery ticket not expecting my sim to win cause my sims never win the lottery. Now she's rich and i've no idea what to do with it lol I'm working on a new house for her but it's barely taken anything away might need to move to a bigger lot and build a mansion. She's also running a bakery where i've transferred some funds too to help build it up but she's still going to have alot left over.
