Tamar Chansky: Overcoming Procrastination: 7 Strategies to Get the Job Done... Today "Bing-bing-bing!" What was that? That's the sound your brain makes when the "finishing things" circuits light up with excitement because you really, actually, finally completed something. It's like an internal hooray.

When I was in graduate school a friend told me there is no greater urgency to clean your house than when you have a dissertation to write.

Avoiding tasks has become so fundamental to our experience that it has been recently dubbed a human instinct. What is procrastination really about?

science encyclopedia How to Learn Without Memorizing Photo by Edwin Stemp Rote memorization is an inefficient way to learn. Just retaining a single formula can mean pounding the same information into your skull dozens of times. Unfortunately, you’re stuck with your brain. A few years ago, I noticed that smart people seemed to learn differently than most other people. While there are undoubtedly some genetic advantages that allow some people to learn effortlessly, I think part of this difference in success comes down to strategy. Is Your Brain a File Drawer or a Web of Ideas? A computer stores information as thousands of electrical 1s and 0s in a linear fashion. However, your brain isn’t a sequence of bits and bytes, so this approach doesn’t make sense. Other Forms of Learning What I’d like to advocate in this article is a more creative, spontaneous form of learning than the style you were probably coached for in school. There are lots of ways you can learn creatively: 1. You can do the same thing with less technical subjects. 2. 3. Examples:

How to Become an Early Riser It is well to be up before daybreak, for such habits contribute to health, wealth, and wisdom. – Aristotle Are morning people born or made? In my case it was definitely made. In my early 20s, I rarely went to bed before midnight, and I’d almost always sleep in late. I usually didn’t start hitting my stride each day until late afternoon. But after a while I couldn’t ignore the high correlation between success and rising early, even in my own life. … and the next morning, I got up just before noon. Hmmm… I tried again many more times, each time not getting very far with it. It’s hard to become an early riser using the wrong strategy. The most common wrong strategy is this: You assume that if you’re going to get up earlier, you’d better go to bed earlier. It seems there are two main schools of thought about sleep patterns. The second school says you should listen to your body’s needs and go to bed when you’re tired and get up when you naturally wake up.

Alternative Sleep Cycles: You Don’t Really Need 6-8 Hours! Most people only think that there is one way to sleep: Go to sleep at night for 6-8 hours, wake up in the morning, stay awake for 16-18 hours and then repeat. Actually, that is called a monophasic sleep cycle, which is only 1 of 5 major sleep cycles that have been used successfully throughout history. The other 4 are considered polyphasic sleep cycles due to the multiple number of naps they require each day. Well the most important of every sleep cycle is the Stage 4 REM (Rapid Eye Movement) sleep, which has been shown to provide the benefits of sleep to the brain above all other stages of sleep. This way, you still get the benefits of 8 hours of sleep without wasting all of the time it takes to get to REM cycles, resulting in a much more efficient sleep cycle. Uberman Cycle: 20 to 30 minute naps every 4 hours, resulting in 6 naps each day. Everyman Cycle: One longer “core” nap that is supplemented with several 20-30 minute naps. Dymaxion Cycle: Biphasic/Siesta Cycle: – Hang in there.
