Glad it worked for you, but that's not how the real world works for everyone.
Some people, even in poverty, are afforded opportunities that some people just aren't. That's fact. And no Tony Robbins, Joel Osteen prosperity gospel, Eckhart Tolle, The Secret nonsense is gonna change that.
Some people will be born into poverty, grow up in poverty, and die in, guess what...poverty! Same goes with being successful and not successful. Working hard is a piece, and a relatively small piece of the equation. Right place, right time, and right influence are probably bigger pieces to the puzzle.
The "I did it, so you can do it too" pep talks people give always comes off as cringe worthy.
