I sometimes steal other people's interesting documents off the printer at work and go back to my cubicle and look them over
Why would you take someone else's documents?
I love stealing other people's work. I love the feeling of success when I look for information that I can use.
You're expected to follow workplace rules while on the job. It's wrong to steal someone else's property.
I do it as an adrenaline rush.
If you are in need of an adrenaline rush than there are other things you can do to achieve this feeling. Try simply getting into a combat sport maybe or going to an amusement park. These are more friendly ways to get that similar feeling.
