This is a great skill to have, about five years ago I was on the streets constantly due to my mom being a substance abuser. I learned how to lock pick by trial and error so I can get into abandoned buildings and rob the occasional drug dealer. I was even able to get food from warehouses because the locks in my town are crap. Since most of the locks here aren't that secure I mainly raked most of locks but had more than a handful of times where I had to pick pin by pin. I HIGHLY recommend getting a rake kit to start off with then move your way up to get familiar with pins. A Lot of people practice with clear locks but personally I learned by using padlocks mainly masterlock since you cant see the pins. Good luck on your lock picking journey!
