It was 1984 when Kolb developed this model, and 1994 when I learned about it. Like many humans, I use tools or practices for a while and even when I'm getting great value from them, I simply stop doing what works at some point. What IS that?? No idea what causes this, but it's insidious in its ability to undo all the good stuff we develop as habits. The only thing I have found to combat this effect is going back to journals I have written for over 30 years.
In my latest perusing, I found the several-year practice of using this learning cycle to speed up my learning during the early days of starting a business. It was an overwhelming time and I needed a process to assimilate all the new experiences I was having.
