So, in order to "combat the urge" I've got this new system: time management. During the day, I list my projects on a new google app that I recently downloaded - a simple checklist. Doing this sounds simple, but it helps me focus on what is important and what is not. Since I'm on my Google homepage all day for email, research, etc. I never miss the list. Next, I schedule time for when certain tasks can be completed. Then, I just make the time... For me, it really is that simple.
