11 Essential Rules Every Programmer Should Live By

I tend to live by rules, many of which I set for myself, and I find that creating personal rules helps me make better decisions without rushing.

Inspired by this, I drafted a set of rules that all software developers should follow.

1: Technology is a means to a solution, not the solution itself

We may be tempted to use the latest frameworks, languages, or operating systems, but they are merely tools; the real solution lies in solving the problem.

2: "Smart" code is the enemy of clarity

Code should be clear and expressive; clever tricks often obscure intent, making maintenance harder.

3: Write code only when absolutely necessary

Write the minimal code required to implement a feature, avoiding unnecessary features that increase complexity and bugs.

4: Comments are the devil

Prefer good naming over comments; comments should only exist when the code cannot convey intent, and they must stay accurate.

5: Know the purpose before you start coding

Understand the requirement fully before writing code; test‑driven development can help clarify intent.

6: Test your code before delivery

Run your own tests; quality is everyone's responsibility, not just QA's.

7: Learn something new every day

Continuous learning prevents skill decay and keeps you competitive in a fast‑changing industry.

8: Coding should be enjoyable

Remember why you became a developer—because you love coding—and keep that passion alive.

9: You can never know everything

Accept that there will always be unknowns; focus on learning what you need.

10: Best practices are context‑dependent

Adapt practices to the situation; there is no one‑size‑fits‑all answer.

11: Strive for simplicity

Simplify solutions whenever possible; the simplest solution is often the best, though achieving simplicity requires effort.
