The document discusses why agile approaches can be difficult. It argues that agile asks people to step outside of their comfort zones as humans tend to be logical, perfectionist, and crave comfort. Some reasons agile is challenging include not having a clear vision, not maintaining a steady pace through iterations, being unwilling to accept failure, and not truly collaborating as a team. However, the document notes that with a shared vision, maintaining pace through small iterations, embracing failure, and true collaboration, agile approaches can be achieved.
