Why Humility Is the Key to Becoming a Great Programmer

I am modest and prefer not to boast, so I quote passages from McConnell’s Code Complete 2.0 to illustrate the importance of personality in programming.

Programming’s intense inner nature makes personality crucial; concentrating on code for eight straight hours is extremely hard, and mental fatigue often forces us to write sloppy code that later requires extensive fixing.

Programming work is rarely understood by others. In many projects we spend 80% of the time exploring interesting snippets and only 20% building the remaining 80% of the program.

Employers cannot force you to become an excellent programmer; greatness depends on personal traits.

Humility tops the list of desirable personality traits.

No one is smart enough to fully master computer programming; how you apply your intelligence matters more than how much you have.

In his 1972 Turing Award lecture “The Humble Programmer,” Edsger Dijkstra argued that most programming compensates for IQ limitations, and the best programmers are those who recognize their own intellectual limits and stay humble.

Good programming habits aim to reduce cognitive load. Humble programmers tend to correct their mistakes, produce fewer bugs, and write code that is easier for themselves and others to understand.

When interviewing candidates, I look for people who are willing to say “I don’t know” when needed; those who claim “I can, I know” are often shallow and risky.

Blogging is a powerful source of knowledge, yet it also demands humility because countless experts share their insights.

Our goal isn’t to be better than others, but to be better than we were a year ago.
