I hated school right up until I got a full time job at 16 and just took my A levels from home. From that moment on, I've loved academics and school, and and those years taught me to go back to Uni and stay in education for as long as possible.
Not trying to sound patronising but when you get a job and experience the inevitable following...
-work over the summer holidays for a few years in a row,
-and christmas,
-and easter,
-sometimes come home from work and do nothing but get ready for another full 12 hour day tomorrow,
-work every weekend for a few years,
-have people treat you like crap the entire time
-and have to do everything of your own accord
-have nobody to go to for help in your work
-get in serious financial trouble if you don't do any 'homework'
You change your world view a bit and realise that actually school was just a laugh with your mates all day.
