"For the earth is full, and there is enough and to spare; yea, I prepared all things, and have given unto the children of men to be agents unto themselves." Doctrine & Covenants 104:17
"Wherefore, men are free according to the flesh; and all things are given them which are expedient unto man. And they are free to choose liberty and eternal life, through the great Mediator of all men, or to choose captivity and death, according to the captivity and power of the devil; for he seeketh that all men might be miserable like unto himself." 2 Nephi 2:27
I'm finding this choice, the choice to be happy, increasingly difficult as our lives get increasingly busy. But when we took our family pictures the other night and the kids were crazy and screaming and wouldn't wear the clothes we wanted them to and wanted to see every picture on the camera after it was taken, we had to do as Sister Marjorie Hinckley says: "The only way to get through life is to laugh your way through it. You either have to laugh or cry. I prefer to laugh. Crying gives me a headache."
