Hey, welcome to the site and such. Everyone gets this lecture so it is not directed at you necessarily...
first off always follow these simple rules:
1) Search before you ask, this makes life better for everyone because there are less repeat threads and we're not answering the same "what is a bump key" type questions over and over.
2) DON'T PICK LOCKS YOU RELY ON!!! This means if the lock is attached to a door, cabinet, vehicle, chastity belt, casket, whatever... unless it is there for the SOLE PURPOSE of being picked, DO NOT PRACTICE WITH THAT LOCK. You CAN and WILL break it... and then your in trouble.
3) DONT PICK LOCKS YOU DONT OWN!!! The only thing worse then breaking the lock attached to your sister's chastity belt is breaking a lock you don't own. Unless you are a locksmith or have EXPLICIT permission to pick a lock, with the owner understanding the lock may be damaged, DO NOT PICK IT.
That being said check out these places for helpful information on getting started.
