tummo

Is that Denali I see?
Ice water immersion.  Yes, that's just like it sounds.  In Finnish it is avantouinti.  If I can't get a sauna, then this is what I can do this winter - cold water dousing also has the effect of elevating body temperature.  The only problem is that it is difficult to keep a large tub of water from freezing solid in the winter here.  But it's not impossible, I could insulate a large tub set in the ground, maybe even have a pump circulate it, but that's a lot of trouble to go through.  I recall hearing about Tibetan monks who do a sort of meditation call “Tummo” in which they can raise their body temperature, especially that of hands and feet, to the point where they can stay outside in the cold, even drying wet sheets draped over their bodies.  This practice is associated with the monk Naropa, Tibetan Buddhism, Tantric meditation, and Kundalini Yoga, but I think that consciously affecting thermoregulation is not a rare feat that requires special training in meditation.  I would guess ordinary folks asked to concentrate on elevating their bodily heat though a kind of biofeedback involving visualization and relaxation are probably capable of doing it.  And this is something I'd like to do, to help me keep a clear mind and good physical health as well as enjoy the outdoors.  Wrapping a thin sheet over my skin could give me some level of protection from instant frostbite. 

If I can develop an ability to generate heat and know my limits, then wearing only a fundoshi I would like to participate on Dontosai, January 14, in the annual hadaka mairi (written 裸参り in Japanese) at Takekoma Jinja in Japan.  It would be a great experience!  I believe it was in 2004, during a visit to Japan that I saw the festival at this shrine first hand.  But first I am going to make my own outdoor shower, and use it until the first frost of the year. 

My greenhouse plans had long since turned to “a plastic sheet covered metal pipe box barely five feet high”, and now my sauna plans have turned to me sitting outside baring my skin to the cold and wet.  And these are my ideas for “the backbone of recreation during the summer and winter - outdoor oriented activities, play in the snow and cold, and in the summer watch plants grow and mold  - social activities, to be shared and enjoyed in the company of others?”  Yes, they are, and now it seems I have it all.

how to implement goals

When it comes to achieving goals, it has been long recognized that simply having goals isn't enough, though it is a start. One way of trying to make goals a reality is expressed with the acronym SMART. According to this approach goals should be: Specific, Measurable, Achievable, Realistic, and Trackable (but you'll find other substitutions for these words as well). I have tried to use this with some of my clients, with mixed results.

I recently came across another method that appears to hold more promise for reaching goals, through the formation of implementation intentions. In short, one makes predecisions of the format: if situation X is encountered, then I will perform behavior Y.  (To this one can add "even if..." and/or "so that I can [goal]" to the end of the sequence.)  This all goes back to self-regulation and the T.O.T.E. model of feedback loops, where an implementation intention defines the "operate" portion of that sequence.  The wonderful thing about implementation intentions is that conscious intent is not needed and goal directed action can become virtually automatic. Since behavioral cues are now in the environment; thinking or reminding oneself about the goal is no longer the primary stimulus for action. It is especially useful for resisting temptations and, by extension, may also be used for impulse control as well. Studies have shown that this is an effective strategy for performing tasks such as math homework, and it can even help six-year olds to not procrastinate. Temptation-inhibiting implementation intentions are not immune to self-deception however, so this approach isn't by any means a panacea.

Here's an example:
Primary Goal: Maintain personal health, and employee and academic performance.
Secondary Goal: Improve my digital media and language skills.
Implementation Intentions (taking only primary goals into account right now):
If dishes have been in the sink for more than three days, then I will do them. If it is six o'clock at night, then I will do my math homework for one hour. If I have documentation to finish, then I will do that at work. If I want to read a construction book, or use the Internet, then I will, provided there are no dishes, math, or documentation remaining to be done and it is earlier than eight at night.

Feedback

In 1943 Arturo Rosenblueth set the basis of cybernetics, proposing that behavior controlled by negative feedback, whether in animal, human or machine, was a determinative, directive principle in nature. Cybernetics focuses on how anything (digital, mechanical or biological) processes information, reacts to information, and changes to better accomplish the first two tasks. It is "the art of ensuring the efficacy of action" according to Louis Couffignal. A premise one might find implied here is that the stimulus behind behavior is the achievment of a goal.

Sound familiar? This has a lot to do with procrastination. In the field of psychology, the importance of monitoring and regulating one's attention to a task prompted George Miller to coin the acronym T.O.T.E.: test-operate-test-exit. In the same breath we could also talk about optimal foraging theory and control theory (a close sister to cybernetics). Each employs a specific example of the classic feedback model. In general terms, feedback is the process in which part of the output of a system is returned to its input in order to regulate its further output. Dare I say it, this is the most important principle for self-regulation in the battle against procrastination. Of course, it cannot address all the fundamental reasons for irrational delay, but it is a very big piece. (Sources: Don't Delay and as usual Wikipedia.)


Postscript 01 March 2009:
In 1973 William Powers built upon ideas like those of Rosenblueth's. He proposed the Perceptual Control Theory model of behavioral organization, which states that living organisms are closed-loop systems that act to keep perceptual variables in pre-specified states, protected from disturbances caused by variations in environmental circumstances. Which makes sense when considering a quote from Claude Bernard (1813-1878): "The constancy of the internal environment is the condition for a free and independent life."
