What I like about Loehr is that he gets to the heart of the matter while keeping it simple. For example: imagine a plus sign as a grid. The top two boxes of the sign contain the phrases, 'positive active energy' and 'negative active energy.' The bottom two boxes contain 'positive passive energy' and 'negative passive energy.' The ideal sector to be in when competing is 'positive active energy.' But interestingly, the second best sector is negative active energy because it's easier to move from one active energy to another. Moving from passive to active is not easy. Before that, I always used to think if you got angry, you were doomed, but if you stay energized, even if you don't act out your anger, you have a better shot of transitioning back to active positive energy.I think I've seen you mention Loehr before. I'll add him to my Amazon wish list. You must have made quite an impression to get a job offer!
I think I've found what I click with now (a patchwork of techniques, but something from the Inner Game has been the biggest). I'd like to think that there's a theoretically perfect structure to it all, but in reality it's probably muchly what I've clicked with. Kind of sad because it suggests it's not necessarily reproducible for someone else.
You may even see some players acting out negatively. It's not something I would want to do but for them, it may be their way of getting themselves moving towards active positive energy.
