I have been doing longer sessions (20+ minutes) with the Muse and am finding that I lose focus mid-way through. Or, maybe more accurately, modules in my mind use the opportunity to force their priorities to the forefront. As described in the Modular Theory of Mind, different modules have developed through evolution to have domain specificity and priorities that have helped us survive in a complex, threat-filled environment. When I do longer sessions, I find that I do well at first and about 10 minutes in, I lose focus and start attaching to thoughts that come up. This morning it was work first, then family, then back to work, then completely unrelated, I started thinking that I should be riding my bike more often and went on a long journey about biking and how great it feels to ride. Anyway, I was able to recover multiple times and had a great session. On shorter sessions, I don't look at the clock. On longer sessions, I tend to look at the clock about 10 minutes in which causes me to lose focus. I am going to continue the longer sessions for a few days and mix them with shorter sessions. The longer sessions leave me with a pleasant feeling for several hours after which the short sessions do not.
