Very good point.
I think Tony is a very entertaining speaker but ultimately what you do with the information he passes on to you is up to you.
People may also find it difficult to take that information and use it because a lot of it is generalities.
Most of the time it seems we need to hear specifics in order for us to be able to use what is being said.
For instance when you add "2 + 2 you get 4."
Instead of if you try really hard you can achieve the goal of finding what 2 + 2 equals but you have to believe in yourself first.
