im one of those people that was in top sets for every subject my entire life, then when i was in year 11 i flunked all the tests smoking pot and kissing girls and fighting bullies, then i stopped smoking, so i got college education, then i smoked, then i stopped then i got a degree, then i smoked, then si stopped i got a job, you see the pattern ?
