The Lord wants you to be happy. I spoke earlier to Randall Bennet of the Seventy and he told me that there needs to be a balance of service vs. self help because the Lord wants you to be happy. He also said that he likes a "good burger" as an example of such.

This was his response after asking if "lust" referred to any desire other than service or fulfilling certain commandments such as being clean, or helping others.
