I discovered long ago that long, uninterrupted blocks of time are more productive than time that's continually interrupted by the distractions of email, ringing phones, and conversation. On the drive from Berkeley to Santa Clara this afternoon, one person said she simply cut off her phone when she needed peace. Another cuts off her computer to avoid email part of each morning. I realized that I'd fallen back into old habits, grabbing the phone whenever it rings, complusively checking for email, and hopping from one project to another. That's crazy. Tomorrow I'll see what it's like to go phoneless for a while and to forget email for the first three hours ot the day.
