Knowledge Is Only Useful When Applied, Knowing How To Apply It Is Intelligent.
I feel like the school system has lead many children to waste a lot of possible intelligence because they are not taught how to apply what they have learnt. The facts we read about in text books may be interesting and such, although those are not significant in the real world. School left me uninterested because many of the things i was learning were never going to be useful or applicable in life. Having all that knowledge is not useful unless you apply what you know into everyday life, although many teenagers do not learn that. Applying your knowledge is true intelligence, not just memorizing the school curriculum, because the real world has no lesson plan. You will never know in advance when a test is going to come and wont be able to prepare, you only have your own intelligence.
