5. Becoming a Programmer To become a programmer you should be an An analytical thinker Programmers need to be problem solvers. The process of programming requires that we systematically break complicated problems down, plan and implement solutions and find / eliminate small inconsistencies in code (bugs). Analytical thinking also manifests in the ability to follow complicated logic through disparate code segments and understand it. It allows us to grasp abstract concepts such as Object Oriented methodology and design patterns and implement it in practice.
