For me, it&#x27;s because I can. When I find a job I do often, I add it to the config, when I find a tool that makes a job easier I pick it up. Bare, freshly installed vim is quite useable, but is missing the affordances of my personally customized environment.<p>It&#x27;s kind of like the difference between being able to cook and walking into a strange kitchen and immediately knowing where everything is. In my home I&#x27;m comfortable, I know that the vegetable peeler is in a different drawer than the steak knives. In a friend&#x27;s home, I&#x27;m just going to have to ask where something is every few minutes if I want to get work done.
