Unproductivity is spending time gossiping in the office instead of doing real work.
Unproductivity is sitting in front of my laptop and not able to do anything.
Unproductivity is having nothing to do in the office
Unproductivity is taking a few hours to get a job done when it can be done within an hour.
And how does unproductivity come about?
It all depends on the individual. I may not be assigned any work to do (well, that's the bosses' job!) but I can DO something else to improve myself:-) I can refrain from participating in gossips, I can refrain from daydreaming in front of the laptop....(guess it's ok to daydream occasionally:-). I can expedite a job and do it perfectly well without having to drag it for hours. Everything's within my control, EVERYTHING. It's all in the mind.

Lapland
Guess what time it was when this pic was taken? Well.....it was around 12.30pm or so in the afternoon. Winter in Scandinavia, Kiruna, the most northern city in Sweden. Long nights and much shorter days, around 3-4 hours of daylight.
I remember when I was in Xinjiang in late Spring, it was the opposite. The days were long; the sun was still up in the sky at 12 midnight...midnight sun.
Anyways, these are the moments that I cherished most!

How The Brain Rewires Itself
Friday, Jan. 19, 2007 By Sharon Begley
IT WAS A FAIRLY MODEST EXPERIMENT as these things go, with volunteers trooping into the lab at Harvard Medical School to learn and practice a little five-finger piano exercise. Neuroscientist Alvaro Pascual-Leone instructed the members of one group to play as fluidly as they could, trying to keep to the metronome's 60 beats per minute. Every day for five days, the volunteers practiced for two hours. Then they took a test.
At the end of each day's practice session, they sat beneath a coil of wire that sent a brief magnetic pulse into the motor cortex of their brain, located in a strip running from the crown of the head toward each ear. The so-called transcranial-magnetic-stimulation (TMS) test allows scientists to infer the function of neurons just beneath the coil. In the piano players, the TMS mapped how much of the motor cortex controlled the finger movements needed for the piano exercise. What the scientists found was that after a week of practice, the stretch of motor cortex devoted to these finger movements took over surrounding areas like dandelions on a suburban lawn.
The finding was in line with a growing number of discoveries at the time showing that greater use of a particular muscle causes the brain to devote more cortical real estate to it. But Pascual-Leone did not stop there. He extended the experiment by having another group of volunteers merely think about practicing the piano exercise. They played the simple piece of music in their head, holding their hands still while imagining how they would move their fingers. Then they too sat beneath the TMS coil.
When the scientists compared the TMS data on the two groups--those who actually tickled the ivories and those who only imagined doing so--they glimpsed a revolutionary idea about the brain: the ability of mere thought to alter the physical structure and function of our gray matter. For what the TMS revealed was that the region of motor cortex that controls the piano-playing fingers also expanded in the brains of volunteers who imagined playing the music--just as it had in those who actually played it.
"Mental practice resulted in a similar reorganization" of the brain, Pascual-Leone later wrote. If his results hold for other forms of movement (and there is no reason to think they don't), then mentally practicing a golf swing or a forward pass or a swimming turn could lead to mastery with less physical practice. Even more profound, the discovery showed that mental training had the power to change the physical structure of the brain.
THINKING ABOUT THINKING:
AS SCIENTISTS PROBE the limits of neuroplasticity, they are finding that mind sculpting can occur even without input from the outside world. The brain can change as a result of the thoughts we think, as with Pascual-Leone's virtual piano players. This has important implications for health: something as seemingly insubstantial as a thought can affect the very stuff of the brain, altering neuronal connections in a way that can treat mental illness or, perhaps, lead to a greater capacity for empathy and compassion. It may even dial up the supposedly immovable happiness set point.
In a series of experiments, for instance, Jeffrey Schwartz and colleagues at the University of California, Los Angeles, found that cognitive behavior therapy (CBT) can quiet activity in the circuit that underlies obsessive-compulsive disorder (OCD), just as drugs do. Schwartz had become intrigued with the therapeutic potential of mindfulness meditation, the Buddhist practice of observing one's inner experiences as if they were happening to someone else.
When OCD patients were plagued by an obsessive thought, Schwartz instructed them to think, "My brain is generating another obsessive thought. Don't I know it is just some garbage thrown up by a faulty circuit?" After 10 weeks of mindfulness-based therapy, 12 out of 18 patients improved significantly. Before-and-after brain scans showed that activity in the orbital frontal cortex, the core of the OCD circuit, had fallen dramatically and in exactly the way that drugs effective against OCD affect the brain. Schwartz called it "self-directed neuroplasticity," concluding that "the mind can change the brain."

Ikea in Stockholm
Didn't get a chance to see Ikea in Sweden. It was closed due to Christmas holidays. What a pity.
Aurora Borealis
Witnessed the aurora borealis in Lapland. Nature is so amazing. Though it was not truly breathtaking, I was in complete awe. While everyone was riding the snow mobile, I actually saw it occurring already... It appeared as flashes of green...but too bad, no other colors like red, purple or orange. Anyways, it was a sight to behold. Hope to catch the really nice one in the near future.
