I've heard it said, if ever you feel sad or discouraged, just start meditating on all the things you are thankful for. An attitude of gratitude or thankfulness can reverse any sorry mood.

Reading through 2 Samuel, I couldn't help but become overwhelmed with King David's attitude of gratitude. And it got me thinking, God has blessed me abundantly more than I could ever need. And as overwhelming as these blessings may be, they are a mere portion of what God does and who He is. I can only imagine what heaven will be like.
