Give up on it for awhile and then look at your game library and decide what sounds fun to play. I recently started playing Mario Golf: World Tour again and having a blast. Didn't realize I didn't complete the challenges and still had a bunch of stuff to unlock. I don't even need nor should I purchase any new games. I bought way too many and haven't even played 15-20% of them. I still have urge to buy new games though.
