But after working on this for many many years, improving little things here and there, then a few bigger things, it became more and more interesting, with a sense of pride that comes with competence and achievement, regardless of the sector.
But if you decide to start a plumbing company in the US, and if you have the brains, put the hard work, talent and discipline to run it very very well even just in a local area, I would not be surprised that you can reasonably become a millionaire over time. Because it's always hard to find a good plumber and electrician. But many people yawn at plumbing, and you'll never be a billionaire. And it will take more than 3 years, and it won't be flip and repeat.
I got lucky with finding that opportunity that really met my skills. But I actually had been looking for one for a while, so it's half lucky. And nobody gave me money. I forced it then, and ever since, because nothing comes easy.
But I am lucky also because I don't have a very strong competition. But maybe because I am in a niche, so not fully lucky?
Sorry for being not very specific in all this...
I also have found that many people are OK to do some jobs for me that I find really really unpleasant. You need to find the right person for the right "unpleasant" though. This is the beauty of capitalism.
And I am now a millionaire. And when I describe what I do, people yawn and don't want to do it. Even if I find it quite darn interesting.
Beware survivorship bias: I strongly believe it is much easier, and way most likely, to become a millionaire if you set your mind to become a millionaire, and not a billionaire. Many more ways and options. No need for a wild unproven new idea.
