Perhaps you think at your best if you are alone, relaxing with 'unlimited time' and not under the watchful eye of the observer/interviewer/boss/etc under a tight deadline.
As one legendary greek mathematician shouted in his bath tub:
Eureka!
So true, when I'm alone its a whole new unshakable me than when I'm my team.
Has anyone thought of including office perk "shower time" to help less productive teams spark up creativity? This has been really helpful for me to maintain stress level of running a startup.
