Hi ladies and gents

Im a newbie to the forum and only just got back into cycling, but I have been talking to a guy at work about clipless pedals which i have never used.

what is the best way to get used to wearing a clipless shoe and pedal?

he has said only wear 1 to start with (either right or left) until i get used to clipping and unclipping it leaves me a free foot just incase i forget, is this a good method? or is he yanking my chain?

thanks
