Why Broken Sleep Is a Golden Time for Creativity
Ideally, when I wake up at 5am and my head is racing with ideas, I head to my whiteboard in my home office. I write and sketch it all down and three hours later I fall asleep again, waking up at 10 refreshed. Most of such work has really been my best, with proposals that were refined and made it straight to top-management. 
In some interviews when the question came 'what do you need to work effectively' I have tentatively asked about this - no early meetings, etc... but there was always pushback. My last company, a standalone Vodafone Group R&D lab allowed all of us researchers these luxuries, but was later consolidated and streamlined.Is there any company that allows people to work this way? What are the best flexibilities that people have encountered? I'd be curious to know....
