英国心理学家哈德飞曾做了这么一个实验:他让3个人在3种不同的情况下,尽全力抓紧握力计。第一次,是在三人清醒状态下握握力计,三人的平均握力为45.8公斤;第二次施用催眠术,说他们极虚弱,结果其握力只有13.2公斤,还不到正常力量的1/3;第三次是在催眠之后,说他们非常强壮,结果其平均握力是64.4公斤,几乎增加了50%。这就是自信的力量。自信,就是对自己的相信和肯定。这对于谁都十分重要。如果一个人连自己也不相信,怎么会有所作为、有所创造、有所建树呢?古代小说家蒲松龄屡试落第,却自强不息,以“有志者,事竞成,破釜沉舟,百二秦关终属楚;苦心人,天不负,卧薪尝胆,三千越甲可吞吴”自勉,终著出名作《聊斋 Haddone, a British psychologist who had done such an experiment: He let three individuals in three different situations, make every effort to grasp the grip. For the first time, the goniometer was held in a sober state of three with an average grip strength of 45.8 kg; the second was hypnotism, which indicated that they were extremely weak and had a grip of 13.2 kg, less than 1 / 3; the third was after hypnosis, saying they were very strong, resulting in an average grip of 64.4 kg, an almost 50% increase. This is the power of confidence. Confidence is the belief and affirmation of oneself. This is very important to everyone. If an individual does not even believe in himself, how can there be something to be done, what is created and what can be accomplished?
