Drivez,
Hours building isn't a waste of time, but if you want to go to one of the bigger schools, it's pointless to do 150/200 hours of PPL flying because it won't help too much beyond the VFR phase of training. I went to FTE with 70 hours on a PPL, now whether that set me apart from other candidates at the job stage, who knows? But to have done that at 16/17 hopefully showed enthusiasm!
