When you are learning how to program, you think that most of your time is going to be spent writing code. The reality is most of your coding time is actually spent reading code. Other people’s code. Code with comments that lie. Code with bizarre short cuts. Code whose original authors are long gone or unresponsive.
And that’s the real skill of a good programmer, the ability to read this kind of code, and make sense of it. Maybe even make it a little better as you come across it.
