Inner Game has been applied to many other areas of performance:

As Tim said in the video “Bounce Hit”, introducing Inner Game,

“Every outer game is different: tennis is different than football, it’s different than making a million dollars in a bank. But what’s the same is our patterns of interference. We take them with us wherever we go. So if you can find techniques and methods for finding the interference, and heightening the focus of attention, then you’ve got something you can use in any outer game you want.”

Tim Gallwey in “The Inner Game of Tennis ‘Bounce hit’”

Selling, teaching, learning are all outer games, and so similar interferences might apply to all of them, making them equally arenas where Inner Game principles and tools might be usefully applied.

Here’s what one person, a former salesman and trainer of sales people, said about selling and the similarities with teaching. What do you think about it?

learning is naturally fun. Being judged by teachers, grades, and tests interferes with the fun. Teachers need to avoid students feeling like their learning is being judged. The teacher needs to learn how their students learn. Students vary in their learning styles and preferences. Some students learn  from visual modalities, other student may be more auditorial or kinesthetic learner. School should adapt to the student’s learning style. Unfortunately, instead students are expected to adapt to the instructor’s teaching style. This is how teaching can interfere with learning just like selling can interfere with buying. Salespeople are taught how to sell at a training that the customer never attends. The salesperson will try to reorient their customer interaction to conform to how things went in the salesperson’s training. This is how selling can interfere with buying.
