Thinking about this as a future business professional:
a) in what ways is "human optimism" important to business success? (and why!?!)
b) in what ways is "human optimism" dangerous, requiring additional realistic or pragmatic care and thought? (and why?!?)
c) Explain how you do (or will in the future) establish a healthy balance between being "over-optimistic" vs. being "appropriately-optimistic".
