New Roman">How High Can You Jump? 中国英语博客基地(English Blogs-英语麦当劳博客空间)!Z&Y6yK&@ H
1A:f7|*Q4Q ? n0 Flea trainers have observed a predictable and strange habit of fleas while training them. Fleas are trained by putting them in a cardboard box with a top on it. The fleas will jump up and hit the top of the cardboard box over and over and over again.
As you watch them jump and hit the lid, something very interesting becomes obvious. The fleas continue to jump, but they are no longer jumping high enough to hit the top. Apparently, Excedrin headache 1738 forces them to limit the height of their jump. 中国英语博客基地(English Blogs-英语麦当劳博客空间)O_9@&p]ej|_3o

When you take off the lid, the fleas continue to jump, but they will not jump out of the box. They won't jump out because they can't jump out. Why? The reason is simple. They have conditioned themselves to jump just so high. 中国英语博客基地(English Blogs-英语麦当劳博客空间)eN7[Vq!o T M

Once they have conditioned themselves to jump just so high, that's all they can do! 中国英语博客基地(English Blogs-英语麦当劳博客空间) p4gIx#q`

^ ^#r v&Q4[:m0 Many times, people do the same thing. They restrict themselves and never reach their potential. Just like the fleas, they fail to jump higher, thinking they are doing all they can do.
