How to boost your coding with a simple note-taking habit - computer programming?

[JustinRT]

Computer programming often focuses on the latest frameworks, but sometimes the biggest productivity boost comes from a simple, old-school tool like a specific text editor macro or a physical notebook for debugging thoughts. What's a low-tech habit that improves your coding?

I keep a small notebook next to the keyboard and before I code I write the problem in plain terms Then I sketch a tiny data flow and list edge cases Seeing it on paper makes the solution feel real and cut guesswork during debugging

Before any commit I write a one page plan with input output and a couple of test ideas If it fits on one page I run with it and it stops me from chasing ghosts in the code

A simple habit is writing down failing tests before running them The moment you see the expected behavior the fix becomes obvious and you avoid blind trial and error

Some teams use a wall sized notebook or sticky notes to map the flow of data through modules A quick glance tells you where to optimize and what to leave alone
