RollercoasterLover makes an excellent point. I don't want the responsibility of all the money in the world. That would make me responsible for the whole world. It took me years in therapy to learn I'm not responsible for everything in the world.
If I had unlimited amounts of money I'm not sure I would do much different. I happily live a pretty simple life. That said I would...
Definitely retire. I'm working toward that now anyhow.
Take another trip to Ireland and invite friends along.
Buy a tractor to be able to do things around the farm like mow.
Have a hurricane shelter built on the property.
Donate money to Best Friends and Alley Cat Allies.
Have some needed repairs done to my house. I would not get a new house. I had my manufactured house customized when I bought it. I love my house.
Buy my best friend a new house or make the repairs she needs to the current one. Whichever she preferred.
Only change to clothes would be not having to wear business casual because I retired. I'm a jeans an t-shirts kinda girl.
Pets would be the current crew.
