Concentration
My concentration soon after Obon which is unique vacation in summer as you may know was horrible.
Originally, my concentration has not been lasting for long time, however, I know my current one was much worse than one before Obon.
But now after 2 days work from end of Obon, I can gradually take longer time to use for investing in myself somehow
Actually, as the satisfaction of my heart, I can realize that I spend fulfilling days.
I try to maximize the amount of time and efficiency everyday so that I make my satisfaction more higher.
