We must be cautious that we truly want what God wants. Otherwise we will twist things to our own way. Each step builds on itself, and you may find the answer becomes obvious at any point along the way. If it doesn't make itself clear, keep moving through the steps until it does. Write down the decision exactly.
Nothing clarifies our thinking more quickly than paper and pencil.
It's said that half the solution is knowing the problem. It is helpful not only to know what you are trying to decide, but why. If your answer still hasn't become obvious, list each option on a separate sheet of paper. Usually, one option will prove itself clearly desirable, or undesirable, at this point. At all times, employ the seven steps of guidance to discern God's will covered above.
