Ben Casnocha blogs about the need for building thinking time into the daily routine. He suggests ensuring that you schedule in time for reading, driving and similarl activities where thinking can happen unprompted. I agree and it is for this reason that I lengthened my morning commute. I now take a less quick but less packed train to work. I have just the right amount of time to sit, read and think about the day ahead, and I still arrive on time. I lose only some fairly unproductive time between 08:20 and 08:50, when previously I would do a sift on the overnight emails to warm me up for the day.
