Jukka,
What is the plus of doing low priority stuff for one hour when you can change the context and do something of more value for you?
Example: You're at work and the most important thing on your list has
to be done at home.
Sub-case 1: The most important thing is 100 times as important as
anything else on your list, its deadline is within 24 hours, and
you have the kind of job where it's feasible to go home in
the middle of the day. Travelling between home and work provides
exercise and time to think and mentally relax.
Sub-case 2: Each thing on your list is about 10% more important than
the next thing, and they alternate between things needing to be done
at home and things needing to be done at work. Travelling between
home and work takes about as long as getting one of the things
done and provides little or no benefit in terms of exercise, relaxation
etc. but is expensive, stressful and dangerous. The deadline for
each thing is in about a week.
In sub-case 1, it's probably good to go home immediately and do
that important thing. That's probably what you're imagining. However,
for many people, most situations look more like sub-case 2.
For me, travelling between home and work usually means exercise and
some mental relaxation; still, it takes time. It's more worthwhile to
get several things done which are of considerable value (though not
the highest value) and get the highest-value thing done later, than
to spend a lot of time going back and forth and get a lot fewer things
done. If the deadline is in a week (or even tomorrow), the thing
can be done just as effectively later in the day, so there's no need
to do them in a particular order.
The value is: if you stay in one context and do several things,
you get more things done in total by the end of the day.
Valuable things.
Doing the most important thing first is a technique. It's not an
absolute rule (unless an individual chooses to make it so), and
it's not the ultimate goal of life. Other techniques, such as choosing
a way to get the most value out of the time available, can conflict
with that technique.
I don't think David Allen discusses in his books how to decide
when to change contexts. I disagree both with Paolo52 and with
another poster on this thread, who said essentially the opposite:
that you stay in a context until you've finished everything to be
done there. The choice of when to change contexts is a complex
decision based on many factors. I don't seem to have much
difficulty making those sorts of decisions.
