Programming: Doing it more vs. doing it better

The character who speaks that line (Polonius) says so in the midst of a rambling and contradictory monologue, though we can certainly give Shakespeare credit for coining it.

I can say from knowing Kragen that there are very few mortals who could run circles around him after 3 years of programming. Trying to imagine what they might be like, Christopher Strachey comes to mind -- it seems he impressed Alan Turing with his first program: https://history.computer.org/pioneers/strachey.html

I think OP has provided good context. But I will try to answer the question you _really_ seem to be asking: unfortunately there is no shortcut.

There are things you can do that will, like the author said, give you faster feedback and thus let you get better _if_ you use that feedback. You might write a lot of code and read a lot of code and internalize good patterns. Eventually you will have enough experience and the confidence that comes with it, to take on bigger and bigger challenges. I don’t know what happens after that for I am still in that stage. But I have observed more experienced programmers and one thing they’re very god at is _really reading_ others’ code thoroughly and being able to spot better ways of doing things (which I imagine is through experience) and also thinking a little bit in the future rather than simply the assigned task. e.g. if assigned to create a new system, they won’t just follow the design specs blindly, but will question the design choices rigorously, helping improve the design a lot, and then implement something a tiny bit better than the eventual design.

Maybe I’m making it a bigger deal than it is, but I’ve worked closely with senior engineers and it’s _always_ a fascinating experience. They will question your design and code very very deeply but all of them will be good questions and will help you either improve your design or not add spurious code.

I used to think I’d get to the point where I could just sit down and breathe out perfect code, but that doesn’t happen. As I’ve thought about the reasons why, I came up with the following reasons:

1. Writing code is an act of inventing. If what I’m trying to build already existed, I could just go buy it and save myself a lot of time and money. It doesn’t exist though. I’m being paid to create something new and unique. This requires thought, trial and error, and multiple iterations to get right.

2. The software development landscape is not a static one. I used to build commercial buildings with my dad. Once I learned that studs should be set at 16” on center, how to measure and cut complex angles, and how to finish cement, I never had to learn those things again. They were pretty much static and I got to where I could breathe out a plumbed wall without thinking about it. In the software industry, developers are constantly having to learn new things. New languages become popular, companies jump on things like Kubernetes because everyone else is, the JavaScript community cranks out new libraries and frameworks on almost a daily basis. While the fundamentals of recursion, looping, and conditionals remain the same, the syntax, idioms, and best practices are constantly shifting. After 30 years of programming, I don’t think I’ll ever stop being an apprentice in at least some aspects of my career.

In my experience, even programmers are poor judges of good quality of code. Usually the criteria they are using to evaluate quality is: "Can I do what I want to do quickly?" This tends to boil down pretty quickly to "Is the code similar to code I've worked on recently?" Understanding the long term consequences of your actions is pretty tough and the ground keeps shifting under your feet. In that environment, having someone else evaluate your performance is really difficult. A manager who isn't actually working on the same code you are working on has absolutely no chance.

Lately, however, I've been trying to shift my approach to design when doing paid work: I try to make things that seem like they should be easy, easy. This is quite challenging in itself, but it's subtly different than trying to write high quality code. My goal is not so much highest possible throughput, or even programming ease. It's to make the process of programming less surprising to the paying customer. Of course, most paying customers have expectations far above what I could possibly achieve, but I see this has allowing myself room to improve.

I believe that if you are able to consistently achieve a result of "projects with this person tend to have fewer problems than projects without this person", it will translate into more $$$.
