I am a zero hit wonder so this may not apply cry

Do something that is completely out of your comfort zone. BiaB is great for that! Take you mind off of writing by reading a book, taking a walk, take up photography or some other hobby and start to train your mind into other things. For example a walk in the spring my generate a song about flowers or lovers or the end of a bad relationship (winter is over). A good sci-fi book or movie may bring up different ideas.

Good luck
