Work expands so as to fill the time available for its completion
There are two synergistic approaches for increasing productivity that are inversions of each other: 1. Limit tasks to the important to shorten work time (80/20). 2. Shorten work time to limit tasks to the important (Parkinson's Law). The best solution is to use both together: Identify the few critical tasks that contribute most to income and schedule them with very short and clear deadlines.
The Law of Triviality... briefly stated, it means that the time spent on any item of the agenda will be in inverse proportion to the sum involved.
One thing about bureaucrats is that they never swallow their young. Leave them alone and you'll find them increasing every year.
Unproductive worry - like Parkinson's proverbial law - tends to expand to fill the time available.
Parkinson's Law is a purely scientific discovery, inapplicable except in theory to the politics of the day. It is not the business of the botanist to eradicate the weeds. Enough for him if he can tell us just how fast they grow.
