She's not the only cost-conscious one-percenter. Warren Buffett, the third-richest man in the world, once bought his billionaire friend Bill Gates lunch at McDonald's with coupons.
Personal finance expert Suze Orman also appreciates the smallest of savings "even to this day," she tells CNBC Make It, adding, "and I am a seriously wealthy woman."
She continues: "We get such joy when we go to the grocery store, and KT [Kathy Travis] comes out and she says, 'Look, because I have this coupon, we saved $2.50.' And we high five each other, because you should always get enjoyment out of it."
No matter how much you earn, it's important to find satisfaction in saving money. After all, the key to saving big is to enjoy it, Orman says. The question shouldn't be, "When can you start enjoying your money that you saved? My question back to you is, 'When do you start enjoying the process of saving?' If you did that, you'll find you don't care about spending money anymore."
