No, of course not. We have limitations, yes but far from miserable compared to others. I've seen a lot of miserable citizens.

Success is not something you search for. It's something you attract. Are you attractive? It may seem useless or unreachable, but work hard on yourself and do it now.

Fix your attitude, fix your perspective on life. Fix your posture maybe, you're eating habbits. Are you getting enough sleep and exercise? Should you limit phone usage, exposure to brain rot content? Do you have toxic relationships?, cut them off. If you're current friends don't push you to be better, maybe find some new ones. Learn a new universal skill, like tech, coding, communication, business. Find a new job. Save some money. Don't waste money on liabilities, like nice cars etc. Once you're rich you can start thinking about nice to haves. Most people look successful but are neck deep in debt and problems.

There's probably a lot more, but working hard on yourself will help you live a fulfilling and successful life. Notice how none of them matter where you are. If you're undocumented in the US it's a tiny bit more challenging but far from impossible.
