Typing between bites of my peanut butter sandwich, until the lunch break is over. Occasionally I'll pop on here during the day as a huge part of my job is solving problems, and sometimes I need to turn my brain "off" from the problem and focus on something else - like winter tires in the thread I just posted in! - and after 10 minutes I turn my attention back to the problem and the solution becomes obvious. This process seems to work for me, for some reason. There's probably a pharmaceutical product that would achieve the same goal but this feels healthier!
