How do people do it?

I saw a video this morning on here where it was a bunch of people on a yacht being asked how many properties they own. Most of the crowd looked to be in their 30s and the average answer was something like 7. This arvo I was looking at listings for 1 bedroom apartments in a suburb about an hour south of the Sydney CBD and they were selling for $750,000. For a tiny ONE bedroom apartment. For all the talk in the media about a cost of living crisis it seems like a big chunk of the population is doing extremely well, and it makes me wonder how they got there at such a young age? Increasingly it's feeling like you're not allowed to make mistakes anymore in life, and that you need to be laser-focused on buying your first property from the moment you start earning money, all while studying for a career that's likely to pay very well, and if you don't follow these two rules you're basically fucked. The standard advice for earning more money is "just find a new job" but when the job market is in shambles right now too it makes me wonder just how most of us are expected to get ahead. Sorry for the rant, it's just impossible not to feel like a failure when you see all these wildly successful people and it's even harder when everything I do to try and catch up seems to fail.
