Take 18 Minutes to Keep Your Days on Track - Time management - Lifehacker

"Basically, you'll start the day off right by grabbing a sheet of paper and writing down the goals which you can realistically accomplish that day. The important part is to immediately assign time slots to those tasks by order of importance and difficulty because these designated times make you more likely to accomplish your goals and give you a way of tracking your progress once every hour. At the end of the work day, you'll take a few minutes to review not just the last hour, but the entire day."
