I think there are different ways of acting 'rich'. There's "Paris Hilton" rich, which is basically just buying pink stuff for your dog, getting drunk and parteeeeh!!! And there's
millionaire mommy nextdoor rich, which is living frugally, but not be afraid to spend your money in wise investments. If you are afraid of losing money and cling to every penny, you'll never be able to make it work for you.
