Finding Financial Success in HTX

I’m fairly new to Houston and work remotely for a job that pays me a decent amount ($70k-$80k range). I’m not struggling financially but I’m aware that any big inconvenience could definitely ruin things for me (as with most Americans). I often hear that there’s a lot of money in Houston but I’m having a hard time wrapping my head around it. My question to those who consider themselves financially wealthy, what do you do for work? How long did it take you to get where you are today? What tips do you have for someone who does not have a financial safety net and looking to elevate financially? I really want to be able to leave something for my future family, even if it’s just a plot of land.
