Time is relative. Two and half years is plenty of time to get a master’s in business administration if you’re going to school full time. But it is probably not enough time to pay back your student loans. And 30 months is definitely not enough time to finish something truly big: like reforming the way an organization with more than 2 million employees, a $700 billion budget, and a 535-person board of directors performs its business functions. Especially if that organization is the Department of Defense.
