Breaking through the next level in life can be difficult. People are slowed down by friction from existing expectations, environment, and externalities. Some of the friction can also be attributed to one's own demons and low expectations. But breaking through is not impossible through a technique called isolate and leverage.
The best way to isolate is to gather as much information as possible. Like water flowing across rocks, the idea is to find and isolate where the water is getting through the rocks. In jiu jitsu, the player takes what the game is giving her, and hones in on the location for maximum leverage.
Then the isolated point is used for maximum leverage. In the water example, it's time to take a jackhammer and push down on the weak spot. In the jiu jitsu example, it's taking the entire body's force and leveraging the weak spot.
