Assertion Example

assert              assert                            @subject.any?     ,"empty subjects"

assert_block        assert_block                      { @subject.any? }

以前是不是有过突然有钻研的劲头,研究完之后又到了三点一线的生活, 其实你有没有发现只有当你有目标的时候你会废寝忘食的去钻研. 这段时间的进步也是不容忽视的. 为什么别人工作干了很多年技术却进步不大呢? 不是说没有热情,而是没有找到适合的学习方法.我就把自己的学习方法都记录在这,以后发现好的都会记录在这.

也许这个'准'字都认为非常的不好找. 其实是你把目标定位的太远了,以至于在想的时候就对做产生畏惧的心理.

认识自己

找到你目前所处的阶段, 不够? 这里
