Too many options

Did anybody have a problem with too many options??? I guess I have always heard people complain about not having enough options. Not me.
I always keep all my options open. I have this strange feeling that if I choose a direction/goal and work towards it, I might end up closing the doors of all other directions and be unable to attain a goal that was meant to be achieved. Result: Did not point all my efforts towards one goal, hence have achieved nothing till date.
I have been doing this since my pre-teen years. And I have also realized that this is one of my biggest weakness (very early in life in fact, sometime during my late teens). But strangely I have not been able to rectify it, till date. There have been so many resolutions made and forgotten, the very next morning.
But then, when I look back, it's not all that bad, I managed to get a decent education, did work for a reputed company, did get married and till date, manage to keep my house in order. To an outsider and a complete stranger I might even end up looking like an decent achiever. But those who really know me ….might be wondering, what the hell is wrong with this girl, why can’t she do something worthwhile. Hmmmm I have the same question. How long before I do something worth my capabilities, how long before I realize that this is ‘the thing’ I was always meant to do.
Or do I over estimate my self???(This is my latest “confusion”). Was my life always meant to be the way it is now. Did I expect a little extra out of myself?
