The guitar and learning to master it!
Everyday we should WORSHIP God by bragging on who He is. A great way to do this is to read the Psalms and jot down on a piece of paper the wonderful attributes of God then tell Him about how Holy He is, how merciful, powerful and so on. Then make another list of the things you are thankful for. PRAISE Him by thanking Him for these things. We are all made in the image of God. Just as we like to be bragged on and thanked, He does too. He really deserves it! We were created to do these things.
