Walk into any bookstore, and you'll see how to Teach Yourself Java in 24 Hours alongside endless variations offering to teach C, SQL, Ruby, Algorithms, and so on in a few days or hours. The Amazon advanced search for [title: teach, yourself, hours, since: 2000 and found 512 such books. Of the top ten, nine are programming books (the other is about bookkeeping). Similar results come from replacing "teach yourself" with "learn" or "hours" with "days."
The conclusion is that either people are in a big rush to learn about programming, or that programming is somehow fabulously easier to learn than anything else. Felleisen et al. give a nod to this trend in their book How to Design Programs, when they say "Bad programming is easy. Idiots can learn it in 21 days, even if they are dummies." The Abtruse Goose comic also had their take.

對于編程，我們現(xiàn)在在大環(huán)境之下，越來越要求速度，越來越浮躁。也許一天學會一門語言確實是可行的，因為你真的會編程的核心思想，語言只是一個工具。

這篇文章的大意，對于我自己而言，大概是。

1、不要光看書，去實踐。

2、不要心急，學任何東西都是一個漫長的過程。

3、有計劃的學，不斷挑戰(zhàn)自己不會的東西。

以上
