This verse is pretty short and simple, but isn't expressing gratitude a sweet and simple thing?
1 Nephi 2:7
"And it came to pass that he built an altar of stones, and made an offering unto the Lord, and gave thanks unto the Lord our God."
When was the last time you gave a prayer expressing only thanks? I know it's been a while since I have. That sounds like a good thing to try today. And because there are so many things I'm thankful for, I should allow plenty of time to do so.
