Setting our hearts

The Book of Mormon is full of stories of men and entire nations who obtain power through unrighteous means, then lose it, then battle to regain it. One such story is found in the book of Ether, chapter 8. A man named Omer has a son named Jared who has a family, and eventually rebels against his father who is a king because he wants to have his own kingdom. He obtains it. Omer's other sons are angry and battle Jared to regain the kingdom. Jared loses the battle and is almost killed. However, the other sons who gave him battle spare his life.
There is one simple yet powerful verse that teaches a very important principle. Verse 7 reads: "And now Jared became exceedingly sorrowful because of the loss of the kingdom, for he had set his heart upon the kingdom and upon the glory of the world."
Interesting isn't it? If there is anything I've learned during my life it's this: Be very selective as to what you set out to gain, because you will most likely obtain it. Whether it's goodness or wickedness, we usually obtain what we want. The powerful thing is that sorrow accompanies the search of wordly pleasures and treasures. Especially once they're gone.
The world today is so very materialistic. If we would set our hearts upon that which will bring us real joy like family, friends, God, and other REAL treasures, ourlives would be much more full of joy!
