Mine are pretty boring, time consuming as well...
Every night I have to press the door 5 times to make sure its shut (don't like having the door open and my windows always open so it could easily swing open) and put a 10kg weight in front of it just to make sure.
I also run my hand across the top of my blinds sometimes to make sure theres no gaps, press on my switches after they've been switched off.
Hate having an OCD, believe me I used to be worse...gradually got better its no laughing matter even though my friends and family do take the piss out of me occasionally I just shrug it off and laugh.
