It’s important to correctly define the YOU in subjective reality. YOU are not your physical body. This is not the egoic you at all. I’m not suggesting you’re a conscious body walking around in a world full of unconscious automatons. That would be a total misunderstanding of subjective reality. The correct viewpoint is that you’re the single consciousness in which this entire reality takes place.
It’s quite clear that success has nothing to do with our initial set of circumstances. Some of the most poor and disadvantaged people in the world have achieved the greatest successes of all time. Oprah Winfrey was born to a single mother on welfare and was physically and sexually abused as a child. J.K. Rowling was divorced, had a daughter, and was living on government assistance before publishing the first book in the Harry Potter series.
