選択と集中 selection and concentration

研究を進めたい．

I want to go ahead with my research.

英語も勉強したい．

also want to study English.

コンピュータ科学も勉強したい．

and computer science.

物理，数学も勉強したい．

and physics, mathematics

ブログも書きたい．

and also want to write blog.

いろんな本も読みたい．

and also want to read many books.

全部はできない．

but I can't execute everything.

ブログは少しペースを落とそうと思います．

I think that blog renewal speed reduce.

コンピュータ科学と物理，数学もいったん寝かせよう．

I will let computer science and physics, mathematics stand.

まずは研究と英語に選択，集中する．

at first, I select and concentrate research and English.

この２つは親和性が高い上に，その他の分野の下地になり得ると考えるからである．

because this two have high affinity and become foundation of other study.

研究７５％，英語２５％で４年間続ければ，

if I stay on research and English at a rate of 75% and 25%, 

研究１００％を３年間，英語１００％を１年間続けたことになる．

I will become to stay on research for 3 years and English for 1 year at full power.

人間もコンピュータも１つのタスクに集中しなければパフォーマンスは向上しない．

human and computer have to concentrate one task, otherwise can't progress their performance.
