My Career: More Questions Than Answers

I tend to know what I want out of life. And if I make a mistake, I correct it as quickly as possible. More often than not, thanks in part to a perfect mix of in-tune instincts and obsessive research, I make the right choices. Marrying the perfect woman. Check. Buying a great house. Check. Landing my dream gig... No check. Why is it that in a world where I am confident about the decisions I make, I am still unsure about my career choices and where I am heading next?
