I think alot of times people get blocked because they try to be sooooo serious.
I write on demand so, it has to flow.
Fortunately, I don't have problems with flow.
I let it all come, goofy, sad, happy, very strange, that is I don't put any demands on the creativity. I don't allways go in the direction I had invisioned but, it is something to add to the comp vault.
Also, this way a person gets used to the way many different emotions feel in a creative way.
Yesterday I wrote a song called "Soapy Titts". Talk about ispiration!
