Hello Eva and welcome to this awesome community! I have the feeling the "American Dream" is some kind of myth. Of course it's hard to become successful. If it wasn't everybody would be. And then I guess it doesn't actually matter if you're in America or some other place to make your dreams come true if you work really hard for it.
I wish you a lot of fun and success out here. If you have any questions or need help within the platform feel free to ask. I'm always willing to help :)
