Efficiency is not your friend!
You can increase your intelligence: 5 ways to maximize your cognitive potential, Andrea Kuszewski, Scientific American (March 7, 2011)
The phrase that I wrote as a title is memorable in the above article.
Long , but not too long in my mind, story is about the intelligence, which is regarded as a connate ability. The author organized five elements below to gain the increased intelligence and/or cognitive ability.
- Seek Novelty
- Challenge Yourself
- Think Creatively
- Do things The Hard Way
- Network
More details, please read this article. Long, but not too long 😉
Most of all, it enticed me with “Efficiency is not your friend …”, being used as a title of this post. I always consider the efficiency when working and living. Using the shortest path to drive to a destination, scheduling my day work in hours, and so on. Because, I want to reduce my wasting, which I generally think about, time to do something else, such as studying, reading, or developing something for the future. But, in reality, I became lazy when I used the remnant time to sleep or playing, which doesn’t mean those are bad, after I had adapted my efficient life ironically.
I think the efficiency for my output is important and more valuable. For my life, however, it makes me lazy. I should evade for me and my family.

<Questions>
- How can it ensure the uniqueness of the block Id? If the block metadata of one node is same with another nodes, would the block Id of blocks that made respectively at each node be equal?
- If an user lost his/her private key, how can he/she find the history or recover his/her value?
