When the desire to surpass your rival (friend or
enemy) motivates you to accomplish the seemingly impossible task/goal you are competing to achieve.
In reference to Dragon Ball charactars;
The painstaking task/goal is generally achieved first by the rival (Goku), which causes you (Vegeta) to accomplish the task/goal out of desire to surpass your rival.
Goku and Vegeta Backstory--
Goku was the first to achieve Super Saiyin (SSJ), leaving Vegeta extremely
jealous of his next level
power. It was an incredibly difficult task to
go SSJ but the burning desire inside Vegeta to surpass Goku allowed him become SSJ without suffering the same strife that Goku had to endure (the
death of a close friend named Krillin).
*John and
Smith are competing in a video game, John is the first to beat a series of difficult missions after several attempts each*
Smith: I couldnt beat it untill you did, then it was
easy.
John: That's the Vegeta effect.
