Adaptability in a rapidly changing environment. This is one of these concepts that is true for Jiu Jitsu as well as many other aspects of life.

“Comfort with ambiguity” was one of the quality most wanted in a large survey of business leaders for the people they hire. (source: forgot ^^…but it was impactful to me so I remembered, and the study was pre-2007). Recently Tobi Lutke (Shopify founder) mentioned something similar in his very interesting podcast with Shane Parrish (#41 The Knowledge Project).

In Jiu Jitsu the “mini-games” we play constantly change at high pace and we must adapt or fall behind. The “main problem” might be their leg one moment, and just as you get rid of it they get a deep collar grip that must now be addressed.
There are several Japanese expressions that I like reflecting this truth.
千変万化　せんぺんばんか Ever-changing (Literally : Thousand-Changes-Ten Thousand – Transformation)

臨機応変 　りんきおうへん　Handling things flexibly, doing whatever necessary given the situation, ad hoc approach (Literally : Face – Opportunity – Answer – Change)

緩急自在　かんきゅうじざい Varying the tempo at will. (Literally : Relaxed, hurried, at-will)

Essentially, to be comfortable with change, you must trust in your ability to handle whatever is thrown at you, which comes from training and mindset.

Map out all the main positions and what your options are from there. Be mindful of where you often end-up, good or bad, and build from there. Better escapes, better counters, better attacks. Build paths between positions (Kimura grip / gift wrap is one great way to cycle between position while keeping control)
