I thought I'd be coding for 8 hours straight. Realistically, I get 4 hours a day of coding, 1 hour for lunch, 1 for coffee breaks, and 2 for screwing around / chit chatting/ stack over and under flowing. Prior to working, I thought that all clients would be idiots and don't know two craps about computers. Boy was I wrong on that one. Sometimes, we get projects by people who can do it better than we can, they just don't have the time to do it. I thought cubicles were bad, Right now I love them :D I actually moved from a door-ed office to a cubicle. I like the openness. All programmers are not athletic. I thought that I was the only one that goes to the gym. Where I work, at least 10 of us go to the gym every day at 5 am. I thought there would be no women programmers. A couple of our leads are ladies.

人们知道他们想要什么。

在很长一段时间里，我以为我会和人们交谈，他们会描述一个问题或工作流程，我将其放入代码并自动化。结果每次发生这种情况，他们以为自己想要的并不是他们真正想要的。

Edit: I agree with most of the comments. This is not a technical answer and may not be what the questioner was looking for. It doesn't apply only to programming. I'm sure it's not my longest-held assumption either, but it was the most striking thing I've learned in the 10 short years I've been doing this. I'm sure it was pure naivete on my part but the way my brain is/was wired and the teaching and experiences I had prior to entering the business world led me to believe that I would be doing what I answered; that I would be able to use code and computers to fix people's problems.

我想这个答案类似于Robin关于非程序员理解/关心我所谈论的内容的回答。这是关于将业务作为一个敏捷的、迭代的、交互的过程来学习。它是关于学习编程猴子和软件开发人员之间的区别。这是关于意识到两者之间的区别，并且在该领域真正优秀，不仅仅是语法和输入速度。

编辑:这个答案现在是社区-wiki，以安抚人们对这个答案感到不安，给我代表。

订阅许多RSS订阅，阅读许多博客并参与开源项目是很重要的。

我意识到，真正重要的是我花了更多的时间来写代码。我有阅读和关注许多博客的习惯，虽然它们是丰富的信息来源，但真的不可能吸收所有的东西。平衡阅读是很重要的，要多强调练习。

Reg。开源的话，我怕我不会受欢迎。我尝试过参与开源项目，大部分都是。net。看到许多开源项目甚至没有遵循适当的体系结构，我感到震惊。我看到。net中的一个系统没有使用分层架构，数据库连接代码到处都是，包括后面的代码，我放弃了。

女人觉得计算机程序员性感……

作为一名老的过程式程序员，当我第一次开始为一个业余项目用Java编程时，我并不真正理解OO。编写了大量的代码，却没有真正理解接口的意义，试图通过将所有东西都强制放到继承层次结构中来最大化代码重用——当一个层次结构无法容纳清理时，希望Java具有多重继承。我的代码成功了，但我现在对早期的东西感到畏缩。

When I started reading about dynamic languages and trying to figure out a good one to learn, reading about Python's significant whitespace turned me off - I was convinced that I would hate that. But when I eventually learned Python, it became something I really like. We generally make the effort in whatever language to have consistent indent levels, but get nothing for it in return (other than the visual readability). In Python, I found that I wasn't doing any more effort than I had before with regard to indent levels, and Python handled what I'd been having to use braces or whatever for in other languages. It makes Python feel cleaner to me now.
