It reminds me of something called "paralysis by analysis". I first heard this phrase when I was contemplating between taking a job or finding scholarship after my internship period finished (ironically, at the time I didn't get both). I forgot the exact quote, but one my colleague told me "not to over think and get paralysis by analysis."
So what is it exactly?
Analysis of paralysis is a condition where you have too many options and thus unable to make a choice. It sometimes manifests when you and your friends are hanging out at the mall, and suddenly one of you ask,"Where shall we eat?"
So far, the only solution I can find for this problem is by being bold and just choose one of the options. It couldn't be that bad, and you can still revise the decision later on. Well, at least it works for small problems. For bigger problems, hmm, wait.. let me think about it first..
