Here’s an excellent short lecture by Sir Ken Robinson (and very funny too – he’s a natural stand-up).
“The school system came into being to meet the needs of industrialisation… You were probably steered away from things you liked doing as a kid on the grounds that you would never get a job doing it. Don’t do music – you won’t be a musician. Don’t do art – you won’t be an artist. Benign advice. Now, profoundly mistaken.”
