You cannot write code if you cannot read the surrounding code. The code you are trying to write today will be hard or easy to write depending on how hard or easy the surrounding code is to read. So if you want to go fast, if you want to get done quickly, if you want your code to be easy to write, make it easy to read.
We read code while we are writing code. Code we have just written will be read by us many times before we commit the code, then yet again for fixes and enhancements. After we write a bit of code, we might read it ten more times within a few hours or days. We read code A LOT more than we write code.
