I'm just curious. Can people be born frugal? I know certainly people can be raised frugal. But we all know people who are very frugal and their family or sibling are not at all. I myself feel like I've been frugal since I was a toddler. My brother who grew up with me in China and lived together for 20 years spend all the money he can get his hands on. It seems one of my sons is born frugal as well. The first time I gave him $5 to spend (he was 3) he bought a pack of candies, a cheap board book and put the rest into his piggy bank. I offered to buy him a new bed several times as he's been sleeping on a mattress on the floor, but he doesn't want one. He rarely wants us to buy him anything and is very keen on saving money.
Has anyone who was not frugal at all achieved it purely by learning, will power and lifestyle change? What's your secret? :)
