Occasionally my job requires that I travel. This week is one of those weeks.
Although traveling is often annoying and can be quite draining - it also creates an interesting dynamic for enhanced productivity. Being away from home removes all distractions. It removes all the usual habits of leisure, comfort, and fun.
Traveling to a foreign city thus creates a short-term boost of productivity. It creates an environment designed for focused work. Over the long-term, travel would have major morale implications - but during the timeframe of a few weeks it can be quite beneficial. Travel time is an output-oriented effect created by the disruption of the norm.
