Jorge Quijano has the weight of Panama's pride and a good chunk of global commerce on his shoulders.

Yet weeks of acrimonious, late-night negotiations to rescue the Panama Canal's $5.25 billion expansion haven't taken a toll on the canal's top administrator, who wakes at 5 a.m. each day for a 40-minute walk.
