I found this video and thought it gave some good counsel from Elder Hales for a place to start in dealing with finances.
The apple for the day is: watch this video and then discuss it! Don't point fingers, just talk about the video and things you would like to apply.
Finances are an easy thing to push aside and not talk about sometimes but it is also crucial that we pay attention and be in control of them too. I am most definitely speaking from personal experience. Work together to take control of them if you haven't already!
