I am a very introverted person, not in the sense that I avoid interacting with others but in the sense that I internalize much of my world. Conversations, problem solving and even actions all take place in my mind long before they are ever manifested into the physical world. I have written this comment in my mind no less than five times over a few hours before I started typing it out. And it's not like I'm refining and perfecting it per se, I'm just having the conversation in my head. Often, these types of "conversations" never make it into the outside world. I'm usually content with the outcome of the non-conversation in my head and don't have as much energy to have the real conversation. So they sit, like unexecuted algorithms, unseen by others. This happens with actions too. I have lots of ideas with general constructs on how they could be implemented yet those ideas seldomly come to fruition. Is it sloth? Perhaps. There is certainly "rust of potential" and a "decay" of inaction.
