1. Listen to a song that talks about the victory won at Calvary (It Is Finished, Calvary Answers for Me, Victory In Jesus; leave a comment if you can think of another good one).
2. Do something for someone else. If you're broke, write an encouraging note to your manager (they NEVER get those!! LOL), loot through through the pantry and make cookies for your youth pastor's wife, or help mom do housework.
3. Read your Bible and pray. Of course, you should be doing this daily already, but it never hurts to have an extra appointment with the Lord. Read about Paul's tribulations, David's woes, and Jesus' miracles; nothing can heal a wounded spirit like the Word of God.
