drilling holes therapy

I don't know why, but I never liked the idea of drilling too many holes into a wall. I'm always afraid that I'm drilling at the wrong place, or that I won't be able to patch it up the same ever again, or that there's some kind of stigma that I'll somehow degrade the structural integrity of the wall.

Plus, it's my mom's house. My room, but I'm living with my parents now, so... I don't fancy drilling holes into other people's walls.

Is there a way to prepare me for my new apartment, where I may eventually have to drill a hole into a wall to put some shelves, cables, lighting, what have you?

Maybe I should just throw away the stuff I don't need first. My room is becoming too cluttered.
