To Think Or Not To Think?

I have often wondered if I have missed out on positive experiences because I overthink and over analyze everything.  
I always have a tendency to assess everything to see if it makes logical sense.
And when I do decide to do something, I always have to have a Plan B through Z.

At tmes I wonder if it's a form of cowardice. 

Why don't I have the ability to take a chance or do something without thinking?  

I feel as though I've missed out in life because of it.
