Do not complicate - One-time variables
We as a programmers tend to complicate things. A lot and very often. There are so many aspects of our job when we gets blinded and do the unnecessary things here and there. This activities introduces complication, distraction and absurdity. For this reason, I decided to start with "Do not complicate" series. First of all, I'm aware that some topics, if not the most, are very basic so please do not call me Captain Obvious, just read on and find out that despite its simplicity so many programmers makes that fundamental mistakes again and again, including myself.
