I have a tendency to do similar things, especially when at work. I've been known many times to forget my cellphone at work and have to turn around and get it. Now I'm constantly checking my purse as I'm walking out the door to make sure I have everything I need before I walk out. Also, I lock my drawers at work every day when I leave and check them at least 3-4 times before I walk out, just to make sure they're locked. I'm constantly checking my wallet to make sure my debit card is in there. The list could go on and on I'm sure.
