A Boy Learning To Cook?

is this a possible for a teenage boy like me??
I've been thinking of learning how to cook in Chezlely Culinary School,,
it's a well known cook school for adult's, teenager's nor kids..
lot's of my friends think that it's a waste of time and money,,
but i think its a cool think to do..
it make's me prepared to cook and serve myself..
it teaches me to be discipline and to be always clean..
so should i or should i not learn in this cook school?
