HMMM. This is something I always ponder.
I think a top 3 is a good way to do it..
First > Homes for my siblings, parents, and myself (definitely with a LARGE reptile room and all my favorite reptiles)
Second > Large lump to save and pass down to the next generation of lil h00blahs
Third > Not sure... As long as my family and I are taken care of, the rest is whatevers. I'll definitely live in a modest house and I'll ensure I have enough money to properly house, raise, and maintain a healthy life for my reptiles (imagine a luxurious tegu cage!).
Everything after that is just extra luxurious. I don't really care about cars. I don't really want a giant mansion that I can get lost in... Imagine cleaning it???... I would probably hire people to invest to ensure my money grows... Definitely must put some funding into anti-pet legislation for my reptiles... IDK if I would just donate to a group of people I've been told to is trustworthy. I'd rather start my own and do it my way with the help of everyone to be honest. I'd probably still work because I love my job. LOL
