I had a lot of trouble with this video. I tried to take it seriously, and I tried to give it a chance, but the more I watched and heard, the more disgusted I got. Positive thinking is a hugely powerful thing, but this is like a bad joke gone wrong. It's time to come back to reality and take a heavy dose of pragmatism.The only "secret" here is the secret of how to make a lot of money by selling people a lot of "feel good" BS. I imagine it's working wonderfully for the authors/creators, while they enjoy our hard earned money.
