Posted on Posted in How To

in the unconscious state of mind, you can pull yourself out and throw out two rhymes and work it back. You get the rhymes first and work it back and then see if you can make it make sense in another kind of way. You can still stay in the unconscious frame of mind to pull it off, which is the state of mind you have to be in anyway. –– R. Zimmerman
