I've watched SEVERAL lockpicking videos and read a few guides you guys got on here along with the MIT lockpicking book thing. And I cant get it. I try and try and try but can't get it. Im picking with a paperclip and a tension wrench from a pen, they work really good and I got my door lock once, but only once

So I was wondering if you guys could give me any tips to get better or reccomandations on locks to start out. Im somewhat limited because my mom doesnt approve of this, I've told her its only a hobby then she didn't say any more. So im somewhat limited on what I use. Thats why I got paperclips.
1st question: Is it the pins that you can see that set on the sheer line or is it the ones above it with the springs?
I'll update with more questions as I come across them. Thanks for your help.
