The world is flat. It's supported on elephants' backs who are in turn standing on a giant turtle.
A lot of people believed that for a long time, and many of them got really angry when people said otherwise. But the ones who didn't believe it found a whole new world.
Whether you believe me or not makes absolutely no difference to me. I won't get rich selling a few books and courses. I'm simply mentioning something that I have found helpful in my life and that others may find helps them.
So chill!
