USAGE IN COMPETITION
A way to impress (and therefore force to surrender or quit) your enemy is to show no-end-in-sight in will, resources and reinforcements. They would not fight till end because they see no end. They will freak out and quit early, very early.
You cannot avoid taking losses but you can reduce their sense of achievement to near zero by quick replacement / rebuilding of what is lost.
You cannot avoid choke points but you can reduce your vulnerability by keeping a stock of redundant candidates that can fill the spot once your only trade route is blocked, your only sea port is burned to ashes or your great leader is assassinated.
Dents in your castle, holes in your formations, fatigue on your face, absence of replacements etc are silver linings in black clouds for your enemy. Prevent or atleast hide them so your enemy never see them.
USAGE FOR HAPPINESS
Any outlet to apparent-infinity at your house is a source of happiness for you. It could be a view of sky or sea or field etc. It not have to be infinite, it just have to appear infinite.
Any outlet to apparent-infinity in your career development is a source of happiness for you. As soon as you see a dead end you lose hope and with it eagerness to work. That is where you end.
Any outlet to apparent-infinity in your hobbies is a source of happiness for you. Sports not work beyond a certain point because its end (world championship) is apparent from start. Arts however provide such an outlet because you can go beyond anybody ever been to.
For purpose of exploration, exploitation and plunder, earth has no-end-in-sight for an individual. Its because in absence of nuking there is no way an individual can exhaust earth's resources. For a sufficiently large group of individuals its not the case even if given whole universe because certain things are available on earth only.
SEVERAL DIMENSIONS
There can be no-end-in-sight in a thing in more than one dimensions. One example is outerspace which has this in all three dimensions. Another example is an empire that may reach a limit on land area because of naval weakness, communication delays etc but still have other no-end-in-sight dimensions such as developing hamlets into villages into tows into cities, technology, arts etc. Yet another example is a person expanding in a hobby though cannot expand in career due to factors beyond his / her control.
IN CV
Suppose you have a topic in your CV, such as Job Experience or Education, that has a size of 1.25 pages. One case is to start it half way on a page, lets say first page and go three quarters on the next page, so it spread from 0.5 pages to 1.75 pages. Second case is to start it on a fresh page, no matter which page, and fill that entire page with it then go on the next page and cover quarter of it. Which approach gets a more favourable approach for you in eyes of reader?
The answer is the second case. Its because it has a no-end-in-sight factor in it. Seeing a page filled entirely by a topic with some part of topic still remaining to be read on next page results in a "sufficient-enough" impression to reader.
IN LECTURING STUDENTS
If you want your students to think a topic is easy enough to be understood, start by showing boundary line of the topic, that way students can see an end. Only then go in detail.
IN ADMINISTRATION
British administrators used to start by taking a trip of land when joining a position. That way they know the limits and can have an easy picture of their duties in mind. Its easier than having a continuous flow of never-heard-before-type-of-problems six months in the position.
IN TASK LISTS
Whenever you have more number of things to do that you can keep in head at one time, write them down. It not matter how complicated or big individual tasks are, if number or count of them is sufficient to result in forgetfulness, make a list of them.
The point of having a list is completeness means that list must contains all tasks. An incomplete list is worse than no list because an incomplete list force you to do mental effort of remembering as well as taking the pain of writing and reading the list.
IN COMPLEXES
A perfectly complex system is such where every part is connected to every other part directly so to understand one flow or one part or one fault you have to understand the whole system. Since as you start at a node (part, flow, path, fault) multiple nodes emerge from it and from each of them multiple and so on so its a no-end-in-sight situation.
A hierarchy on the other end is dead easy to understand because only a few number of things need to be kept in mind at any given time.
IN COMPUTER PROGRAMMING
Any method going beyond a page has a no-end-in-sight factor. Any class having list of methods and fields (one at each line) going beyond a page also has that factor. Any project having list of classes going beyond a screen full of list also has that factor.
This factor is also present in tables that have columns going horizontally beyond width of page.
RELATION WITH NUMBER SIX
The number six is the ultimate number of things a person can handle at a time without grouping. Beyond six we cannot imagine directly i.e. primarily i.e. without grouping. If you have seven different problems and you cannot group them in one heading such as related-to-work, related-to-finance, related-to-family then you get overwhelmed. If six different enemies operating independently attack you simultaneously then you are almost guaranteed to be stunned and defeated. This is why guerilla wars are effective against a very large and organized army. Its because being organized it has to be handle by only one leader whose brain can be easily exhausted by attack at more than six places and being large it cannot be hidden.
Btw, there are only two strategies to handle guerilla war if you happen to be the large and organized one. First is to decentralize and divide yourself in small groups and the other is to focus on one or two goals at the cost of the rest.
IN MANAGEMENT
No manager can actively administer more than six subordinates without having either assistants or grouping subordinates in bundles managed by higher subordinates.
IN MACHINE OPERATORSHIP
No machine operator can actively read more than six instruments.
