Additional needed skill

Once you catch the idea, you could this way shorten your working day to 4 hours a day 5 days a week, if you get paid by the work done and not by the time consumed. If you are intelligent and have wisdom of life, you could in such work shorten your working days even more, but that requires more skill.
Anyway, once you get your work done quicker with more intelligence and skill, you are left with the problem of communicating with the slower witted fellow workers. For that have the idea that you want to communicate in your mind, picture it as a clearly sensed landscape like picture in your mind and see it in as great detail as the others comfortably think about things. Then just write it down or tell it to other in such smaller size bunches as they are comfortable with. That's it! You have thus mastered communication between different levels of intelligence.
For example in thinking work, the new idea may take just seconds to think thoroughly through with good quality, but writing it down may take a half an hour or even two hours, if you want to communicate and teach clearly and friendlily. (The more intelligent ones are easier to bear if they are not a burden but cause only a little bit of not so tirying work with which to avoid masses of extra labour.)

Relaxed reactive body increases intellectual capacity

The body and mind are connected via natural gestures expressing one's present state of mind. If one is stuck to habits, for example concentrated single-eyedly to certain task, then one's body too is restricted to certain posture with certain kind of movements only. Like fixed ways of thinking get expressed as fixed ways to keep one's body, likewise new ideas come much more easily when the body is relaxed and reactive, like is typical in friendly social situations where one tries to see things from the points of view of others too. The thus gained freedom of movement gives freedom for thoughts and so one's understanding becomes much better.
New ideas demand a change in one's attitude, which in turn is expressed as a change in one's habitual posture. Ideas sink in typically only after the body has been relaxed and reactive for a second or two. So much quicker is one's understanding when one's body is relaxed, lively and reactive.So practising relaxed nice sports which have lots of variation and demand reactivity, can increase one's intellectual capacity substantially.Reactive here means reactions that make sense according to each situation and not just messing around without any clear idea of what makes sense in such a situation.
