心理学家有说过，拖延症是种自我保护，并不是精神疾病。现代人处在日益激烈的竞争环境中，产生很大的“评价压力”，一些人恐惧自己没能力面对，于是选择拖延，因为拖延会带给人“掌控感”，也就是说即使最后失败，也可以给自己和他人一个合理的解释，一个台阶下。

A psychologist once said, procrastination is a form of self-protection and that it is not a psychological disorder. People nowadays live in an ever more competitive environment, putting a lot of pressure from criticism, some people fear that they won't be able to measure up, so they choose to procrastinate, because procrastination gives them back a sense of control, so that even if they fail in the end, they can offer up an explanation to themselves and to others, an exit strategy.
