What role does luck play in life? How does luck relate to fate, and how does all of this tie back into what we can and can’t control? We’re discussing it all this week with Maria Konnikova, author of “The Biggest Bluff.” She talks about what good investors have in common, and the truth behind the “illusion of control.”  We discuss emotions, and why they’re so critical to our decision-making process, and we get a crash course on how to bluff — and how to know when we’re being bluffed. In Mailbag, we talk aging parents, target date funds, and caring for a significant other financially. In Thrive, should you take a gap year if your college is closed this fall?
