When I think about how to use time, think about the work efficienfy in time. Time work efficiency is defined as the work divided by time. For example, supposing that there is a regular monthly hourly priced work, how can I get two digit more results than the regular work? No one can perform 10 times jobs at a same time or work 10 times faster than a regular job anyway. If the result of work done is the same, we only have to shorten the time, but we can not make time goes be earlier or late as long as we are human beings, and it is equally consistent for everyone. Then, how about the idea that it is better to have more than one result obtained in one process? I call It as "leveraging a time".

What if I could use the result of the work in the same scene when I did a job? How about using it as a team's asset and using it by 10 person? Even if I spend more time than normal work on such work I will get return more than 10 times. Finding more universal theories will be more widely leveraged, so researching universal methodology and leading practices such as SRE or LEAN will broadly improve the quality of work and influence. It is also worth doing so spending more time will not spoil the value of time.

In the early 1990's, it was good approach to fix the sample source code of the existing transaction processing. However, at that time having questionier to given code, learning the principles of transaction processing, database design, theory of set foundation etc, these old knowledge are useful when a completely new transaction system like block chain comes out . In this way, considering leverage in a wide domain of target, it becomes long-term fundamental knowledge. Exploration of engineering and scientific facts forms a more generic foundation for work results. Also, regardless of discipline, the world of liberal arts gives us the ultimate general knowledge. Such generic knowledge gives great influence not only to the work rate but also to our existence so that even if I spend most of the time of life the value will not be compromised.

There is a way of thinking differently for each individuals, and there are approaches to consider priority on the basis of direct effects. That is also nice. I like approaches that help teams and communities.
