This is a really important aspect of seeking wealth that many people don’t understand. The jump from poverty to no longer missing bills is much more significant than the jump from middle class to upper class. It’s the reason why so many studies exist showing that past $75,000 per year (not inflation adjusted, so try $120k or so), more money doesn’t tend to make you happier. Instead, you trade freedom and happiness for the money you thought would bring you freedom and happiness. Also, trying to become a billionaire is most definitely a lonely and sad path.
A somewhat healthier goal would be to become “financially free,” whatever that means to you. No longer needing to work, allows you to do the work you actually love.
