I just read an interesting article on how removing options actually makes life a whole lot simpler. Closing Doors
Decisions Decisions... from a leadership perspective, you're better off making a decision and sticking to it to show that you actually have an opinion, and that you're actually choosing a direction rather than wandering around aimlessly. Irregardless of the rationale that went behind the decision itself, people would more likely follow someone who believed they were sure - rather than someone trying to hold open ALL of the doors.
From a personal networking side, it's not a question of whether or not you are allowing a door to close or not. You just have to keep all of the doors slightly ajar, and failing that, you just have to remember where the doors are, and which door does what. For in this arena, a door is never closed unless you've completely burned the bridge.
Lastly from a marketing perspective, you will ALWAYS make more sales with more than a single choice, as now your clients see some sort of selection, but there is a barrier that once you cross over into TOO MANY choices, people will simply stop purchasing things because they now need time to think about it more, and with too many decisions and distractions in life already - if it slips their mind, you've lost the opportunity.
I think I'm working way too much these days...
