I wanna start clicker training, but I can't! Please help! Any info!?!?!?

The coke can is a lot harsher sounding than an actual clicker. My opinion in the clicker is that its just pointless. They say its supposed to let the dog know that they performed the task properly. But you could just as easily give them a treat or say "yes." I've trained tons of dogs and never used a clicker.
