My brain is constantly in an obsessive state, meaning that I get an obsession about something and my brain just focuses on that single topic for some variable amount of time (days, weeks, months) until I get a new obsession. I'm quite unable to think (or do) anything else during that time.
Last November I experienced something that I have not experienced before. My mind was at peace. I had no obsession for at least two weeks. It felt amazing, I was so content.
I started to read Wizard of Earthsea, which I finished few days later. Then I read Tombs of Atuan in a few days as well. I read The Farthest Shore about halfway before my brain rebooted into its usual obsessive state. This was the most I'd read in almost 10 years!
I wish I could experience that peace of mind once again.
