I found a typo in Line 23 (which might have been made deliberately by the author who does this in a bit to checking if there are as many readers and serious readers as he expected):
' 正如之前所说的那样,想要改变生活,就要改变观念。从现在开始,请牢牢记住,“速成不绝可能”。如若真的相信这个简单的道理,就不大可能懈怠,因为相信这个道理就等 ··· ···'
“速成不绝可能” should be rewritten "速成绝不可能"
