We really need to pull back and consider what training is. A lot of the times we are drawn to the trainer and their thoughts. But then what is a training, and what is a glorified meet and greet?
You have this experience too. Much too often, people come out of training and talk so much about what they learned not how they changed from it. There is a big difference.
Some training has an exercise or take-home message of putting it into practice (the currently trendy word is “praxis”). Some people carry this out, and others learn to talk about putting things into practice.
