So here's the thing: spending your day at the temple is absolutely marvelous.
Nope, not kidding. I was at various temples, or driving to them, for several hours today. I visited 3 different temples with some wonderful girls.
Some people worry that when you visit several temples in one day, you miss the point of going to the temple. You start to focus on the number of temples you can go to instead of feeling the Spirit. However, I didn't have that problem. Each temple we visited was it's own uniquely beautiful, soul-cleansing experience. President Gordon B. Hinckley says that each time we visit the temple, we leave a better person. THIS IS TRUE. The temple strengthens you and helps you to be strong in the gospel.
Moral of the story: the temple is incredible. It's a sanctuary, which is defined in Webster's Dictionary as "a refuge for wildlife where predators are controlled and hunting is illegal". Sounds weird, I know. But seriously--predators (Satan) are controlled and hunting (Satan trying to pull you down) is illegal. It can't happen! Go as much as you can. You will become a better person. :)
