I have been journaling consistently for two years now. One of the benefits of this log of thoughts is seeing the trends and patterns in my thinking. In particular I've begun to notice that certain ideas pop up in a correlated fashion. The correlation seems related to the underlying frame and perspective I'm orienting to the world with at that point in time; aka my mindset.
There's nothing too revolutionary with noting I think different things depending on my mood - it'd be weirder if I didn't! But since improving my thinking is something I want to do, I think it's valuable to lay out what a mindset is and how it affects my thoughts.
A mindset is like the space in which thoughts emerge and interact. Certain thoughts are native to certain mindsets, and arise more easily in those mindsets. For instance if I'm operating from an angry mindset, thoughts that are tied to that attribute - yelling at someone, fighting someone - happen more frequently. It's like the activiation energy for those thoughts is lowered.
Mindsets are characterized by being multi dimensional. It's not just that when I'm feeling happy, happy thoughts arise. It's that I'm feeling happy, motivated, serene, and inquisitive. This collection of attributes seems to be one of several "resting" places for the mind – it seems like I'm more likely to end up in one of these regions instead of in a random place drawn from a uniform distribution of attributes.
Mindsets are transient, with different ones arising over time and in response to environmental cues. Mindsets are, in the OODA loop terminology, my orientation to the world. Sidenote - though that's just one frame on mindsets, there are many other analogies I could use, depending on the mindset I'm in when I write this
Many productivity rituals - like a writer putting on a specific song before they begin - seem to follow a trigger-action pattern, where the environmental cue triggers the mindset for the activity. Similarly many tips for self-control are constructed to compensate for the decrease in required activation energy in a given mindset. Think of the advice to count to ten before saying something when you're angry.
I'm particularly interested in this because I think mindsets are often overlooked by standard productivity advice. As Suchman notes in Plans and Situated Actions human behavior is rarely the result of the "classical rationalist" approach where a person 1.) thinks up a plan 2.) executes the plan. Rather we draw upon the context that we're in, and the rich awareness of the world that provides, and then employ plans as one of many mental tools. So getting into the right mental context, the one which fits the task and the goal is key for taking the right actions. I bet for most knowledge work it is in general more effective to get in the appropriate mindset than it is to try and execute the right plan.
Mental moves to make it easier to smoothly transition into a new mindset, or let an old one go if it's no longer appropriate to the situation, are valuable. I suspect a lot of the value of meditation comes from making it easier to transition between mindsets.
