I am convinced there are many things I could have learned. The fact of the matter is, it all comes at a price. As a CO once inquired after my willingness to serve at bethel, I responded that I'd rather stay in the trenches than living in an asylum called bethel, insulated from the real world.
So maybe, I could say that I've learned not to be impressed by position and pressure.
Further, I am not haunted by nervous breakdowns when I have to make a presentation, whether the audience is only one person or a larger group.
On top I should say, comparing a lot of sales tricks with the KM presentations, I found a lot of similarities. So, exploring that avenue brought nothing new in the sense of format. It has brought new insights as to why! and that's something the WTS doesn't tell you.
Come very handy in my line of business.
