Alex's brother wanted to drop out of school, and he asked for my opinion.
"He should."
Not everyone is cut-out to study, and therefore not everyone excel in it.
But that doesn't mean he's doomed or prove him a failure.
People can be stupid and do well in exams: they're just exam-smart; pure nature.
But most people the other way round: smart, but fail exams
(at least most that I see around)
I never think any one is stupid or retarded; it's just how wisely they use their functioning brain to do things they're born with an instinct to excel in.
Brace yourself, look into the mirror; ask yourself "what".
