今天想谈谈 关于问题,什么是问题,如何去定义问题,如何正确认识问题,如何去解决问题。
到底什么是问题,百度了一下,里面讲到,问题是现实与期待之间的差距,解决问题的方式有两种,一个是降低期待,一个是改变现实。随着总结的深入,我也发现了自身的许多问题,那些问题被我解决了吗,显然没有,我也想着去解决这些问题,但最后非但没有解决,新问题反而伴随着旧问题的产生,那些旧问题被搁置在一边,然后在今后总结时发现又是老问题。解决某个问题,需要某些方法去解决,比如,如何通过某种考试,拿到证书,如何能做到天天早起。这确实需要某些方法论,但会不会出现某种情况,当你把你能用的方法都用尽了,但是这个问题都没有解决。有没有这种情况我倒不知道,不过,爱因斯坦曾讲过这么令人匪夷所思的话:“所有困难的问题答案都在更高的层次,你必须提升心智,认知,层次,才能解决问题。”难道说,比方法论更重要的是,提升心智,认知,层次?让我印象最深的是玩游戏这件事,初中的时候拿到手机特别喜欢玩游戏,那时,我多想长大,长大后玩手机,玩游戏也没有管了,想怎么玩就怎么玩,如今,对游戏也没什么兴趣了(可能是操作太菜了)。当初的苦恼,现在看来完全不是个事,还用的着用啥手段去抵制吗。可能爱因斯坦说的这句话还是比较有深意的。
