Arno Minkkinen dramatizes this deep truth about the power of patience with a parable about Helsinki’s main bus station. There are two dozen platforms there, he explains, with several different bus lines departing from each one—and for the first part of its journey, each bus leaving from any given platform takes the same route through the city as all the others, making identical stops. Think of each stop as representing one year of your career, Minkkinen advises photography students.
