That is half the fun...
I spend way too much time considering things if I have a large selection of choices.
Say something as simple as going to subway freaks me out because there is too much choice. Having to think about which of the 30 fillings I want and then if I want it toasted or not, It's just so overwhelming.
At some point I just cut my mind off from the decision and basically pick stuff at random otherwise I would be there all day considering the options. Either that or If I am leaning towards something I "lock it in" so I can't change my mind about it anymore.
