I feel like I forgot to say one of the most important things about making decisions: that God loves us, cares about our lives and decisions, and both wants to and will help us and guide us. He's promised us that. Seek and ye shall find. I will send you my comforter. The Holy Ghost "will show unto you all things what ye should do" (2 Nephi 32:5). We can trust in His promises and in His guidance. He will nudge and help us along, because He knows us perfectly and has it all figured out.
We are so lucky He doesn't make all our decisions for us, and that He doesn't give us everything we think we want.
