At one time, I used to have a favourite text editor and a favourite programming language, but I had one issue I have got emotionally attached to them and why was that an issue? It was an issue because it’s caused me to have an inflexible attitude, for example, I couldn’t work with a certain company or clients because they want me to use a certain programming language and then I realised if I learned only one programming language and not anything else, I would have got stuck in a rut and that not really a good thing, I really don’t want to be in that position.
