Good web navigation design is not about giving people lots and lots of choices. It is not about second guessing decisions we have made. It's not about asking what if we want to get back to where we were. It's about looking forward, not about looking backward.
Your job is not to design for all possible directions someone might want to take. That leads to a cluttered website and it will clutter the mind of and overload the attention of your customers.
Your job is to understand the primary direction your most important customers are heading, and to remove obstacles in the way of them arriving at that destination. Forward-looking navigation options should dominate.
