I've started doing something new that seems to be quite helpful. I'm sure lots of people already do this but I am surprised at how effective it is. Instead of doing things quickly and stressing to get them over with ASAP, like I have always done, I now try to do them slower. I believe forcing yourself to do things a little slower makes it easier to concentrate, easier to zone out when doing boring tasks, and easier to enjoy whatever you're doing (hell I even enjoyed doing the dishes yesterday).
