Programming is mostly about reading previous code, researching what is needed and how it fits with the current system, and planning the writing of features with small, testable increments. The actual writing of lines of code is probably only 10% of the whole process.

Samer Buna

Do not think about programming as writing lines of code. Programming is a logic-based creativity that needs nurturing.

Samer Buna

Planning before jumping into code is a good thing, but even good things can hurt you when you do too much of them. Too much healthy water might poison you.

Samer Buna

Do not look for a perfect plan. That does not exist in the world of programming. Look for a good-enough plan, something that you can use to get started.
