As a young professional, just starting out, I'd have to say that I'd want to see what I haven't seen before. Travel, travel, travel. Although, having not been in the workforce before, I haven't really seen anything past academics. I'd want to have a balance of everything: Travel, family, friends, work, and relaxation...but isn't that what we should strive for anyways? When you compress your life into a decade or less, it seems short and rushed, but in reality, it really isn't. Great question to think about and ponder!
