Too many programmers read articles like this and assume that they are the 20% of good programmers while everyone who disagrees with them is the 80% of amateur developers:
> I have worked in software development for 20 years, worked on many projects with many software developers. I estimate 80 percent of software developers are amateurs and 20 percent professionals
Yes, it’s true that some programmers deliver better results than others. It’s also true that some have better methods than others. However, this is one of those situations where if you pulled developers aside and asked them to rank themselves relative to their peers, you might get 80% of people rating themselves as above average and 50% of people claiming to be in the top 20%.
A common pitfall I see is when developers forget that the goal is to ship software and instead focus on doing everything the most correct and perfect way they can think of, regardless of their resources. I’ve worked with many teams of professional programmers who spent so much time perfecting their tooling and code and architecture that they rarely ever shipped anything. Learning the tools of the trade is important, but don’t lose sight of the goal: We need to strike a balance and get work done, not just perfect our craft in a vacuum.
