To  be  perceived  as  fluent  in  conversational  Spanish, for  example, you  need an active vocabulary of approximately 2,500 high-frequency words. This will allow you to comprehend more than 95% of all conversation. To get to 98% comprehension would require at least five years of practice instead of five months. Doing the math, 2,500 words is a mere 2.5% of the estimated 100,000 words in the Spanish language.

This means:
1.  2.5% of the total subject matter provides 95% of the desired results.
2. This same 2.5% provides just 3% less benefit than putting in 12 times as much effort.

This incredibly valuable 2.5% is  the key, the Archimedes lever, for  those who want the best results in the least time. The trick is finding that 2.5%.

Where else does this apply? Is there a 2.5% of Jiu Jitsu that will handle 95% of the situations you end up in on the mats?

I believe there is, but like he said the trick is finding that 2.5%.

I do things a bit differently. Four and a half years to blue. At this rate I’ll be a black belt in 2050. I’m okay with that.
