Dallin H. Oaks taught,

The Spirit of the Lord is not likely to give us revelations on matters that are trivial. I once heard a young woman in a testimony meeting praise the spirituality of her husband, indicating that he submitted every question to the Lord. She told how he accompanied her shopping and would not even choose between different brands of canned vegetables without making his selection a matter of prayer. That strikes me as improper. I believe the Lord expects us to use the intelligence and experience he has given us to make these kinds of choices.
