I think a lot. I don't stick to a view or idea. This makes me passive because it gives me options. Constant process of going back and forth.

When I sleep 3 hours instead of 8, my brain activity decreases next day. I experienced that I am more happy and active those days even if I'm tired as fuck.

Besides inhibiting my brain functions, do you know of an actual way to decrease thinking? Meditation helps a little bit. Been doing for months.
