This question is most commonly used in relation to how we feel about a past situation. What if we invested in Google/Amazon/Facebook 10 years ago? What if we asked that girl out sooner/later? What if we played football instead of soccer growing up? What if we took that other job? All these questions are about situations/encounters/decisions that we cannot control. They destroy our time, energy, and most of all, our future goals/aspirations. While we are stuck in this ‘paralysis by analysis,’ we are wasting perfect opportunities to make the next best decision.
