Learn to live in a way in which you have no enemies to struggle with and no battles to win.
The most impressive sentence from the book called "In praise of wasting time" which I read in Vancouver during the time I was feeling spending no productive days.
This sentence was quite sensational to me.
Through my life experience, I did play sports all the time.
And I thought the only way to get satisfaction was to win.
So I sticked to win and always battled to others.
But from this sentence, I realized that we can feel happiness without winning or beat enemies.
Do not need to compare with others or be superior.
Just concentrate my life and go my way.
