These weak sauce sources are better than any (read: none) sources you've been so kind as to share. To your point, I am better at mindful activities when I'm alone in my quiet home office with a comfortable chair than I am in a noisy cube farm with Jeff trying to talk to me about his weekend plans or asking me to head to the next-door Mexican restaurant for lunch. Plus, I work longer when I don't have an hour of commute to worry about. Eat breakfast and I'm ready to work.
