I’ve started evaluating what seem like brain “modes”. 1. Constant flow of information with disjointed context (social media, brain fracking, moving in a crowd) triggers hunter-gatherer instinct that is hard to stop. The dopamine seek in a way. Even if you stop your brain seeks it, so unless you really need this mode for work, it helps to postpone or time box these to the end of the day (kind of like some would do with drinking alcohol).

2. How you start your day after sleep creates framing of the brain and you can start iterating on frames and how you drive them depending on your needs. Maybe set a schedule of things to at need done the night before (a continuity thread) maybe boxing the activities to different types at different times. It’s all sciencing the self but the brain is definitely conditioning to things and you have to mind it.

3. ADHD meds from what i’ve read are caffeine on steroids (blocking adenosine receptors, but not really adding to executive function). From personal observation ADHD also feels like a mode one can be put into by wrong brain framing (at least for people not diagnosed).
