The biggest.
Throwing out another key tool for the brainiac (for whoever needs to see it): microdosing mushrooms.
Microdosing creates new neural connections across the brain and between hemispheres, increases neurogenesis+neuroplasticity, and has spiritual benefits associated with temporarily slowing down the default mode network (where we hold identity).
I’ve been microdosing on and off with some solid 6 month breaks for about 7 years — fully shifted everything about me.
