What are the facts, the data behind evaluating which car to purchase, which city to live in, which job to accept or reject, what business you want to start or what college you should attend? Gathering the facts and figures is critical to moving beyond your feelings (which can be fickle) to having some hard evidence behind your maybes, yes and no(s). The data presents the statistics, figures behind every option. The data in and of itself, can't determine the right course of action for you, but the facts help you build a case, or paint a picture of the details behind each option you are considering.
So when gathering evidence, do your due diligence to ensure that your sources are credible while keeping in mind that these pieces of information are leading to the puzzle (of indecision) finally being solved. Evidence gathering in the decision-making process will end up empowering some of your options while closing the doors to others.
