When analytically-minded people hear me introduce the third element of any decision, information, they often light up with validation.
"See! So I am right to take my time in analyzing all the information."
Not quite. Good decision making does require an evaluation of information on how various options may help you met your objectives. It doesn't, however, justify putting off making a decision until you've analyzed all the information. This is one of the distinctions between the decision engineering I learned in school and the applications of it I studied in the 15 years since.
In personal decision making, you will never have perfect information. The key to making a decision isn't waiting until you've gathered all the data. The key is knowing how much and which data you need to comfortably move forward.
