有時我地會同朋友坳一啲小事 例如邊個notebook型號好啲
而我地一直都想用唔同嘅evidences去坳贏其他人
但係個作者話坳贏左又點
因為唔但只嗰個人會frustrated
而且佢都未必會因為呢次argument而改變想法
（因為人固執 永遠都係信自己嗰套
That’s why 個作者第一個chapter就叫人Don’t criticize, condemn or complain.
所以本書入面有一句好正
“remember we are not dealing with creatures of logic. We are dealing with creatures of emotion, creatures bristling with prejudices and motivated by pride and vanity”
“Any fool can criticize, condemn and complain—and most fools do.”
可能睇嗰陣咁啱同朋友都有啲argument
所以上面個quote好深印象
