There are two things that practically every rich person I've met have in common (where rich is assets over about $100m that aren't inherited). The first is focus. They have the ability to see an idea through to the end. They believe in themselves, they believe in an idea, and they execute. By the sounds of it noduerme might have that sort of focus. To live frugally when you don't need to sounds like someone who has an idea and is sticking with it. That's awesome.
The second thing is need. Actually needing money, either just to start out, or to fund a lavish lifestyle, or to keep up status, is a powerful driving force. Setting up your life up in a way that removes the force stops most people executing on their ideas.
This is advice for anyone who wants to get rich - if you slowly grow your assets to a point where you're very comfortable, you probably won't ever level up to the point where you can buy a Lamborghini because you just won't need to. If your goal is to become rich most people don't seem to be able do it by slowly growing their wealth and then working on an idea. You have to use the need to be "%^&* you money" rich to drive your idea.
(This isn't universal of course. Some people come up with an idea later in life after they've got a house and assets and still execute brilliantly. But it's much more common to see younger founders who need success pushing an idea to a big exit.)
