What is the logical rational first thing that needs to happen when you are making a significant life or business decision? If you have a preference for Thinking, your answer to this question might just be that you need to identify your criteria for a successful outcome. That way you will be able to compare and decide if the option before you meets that criteria.
While this makes sense in theory, in practice someone with a preference for Feeling will typically have a different approach. They may eventually come up with a very rational and objective set of criteria but a more subjective approach will lead them there.
