Heart or Head?

So I know that it's been awhile since I've posted anything here and I would love to make grand excuses for why that is, but I have none.  I could make something up, but that would be unfair to all who read this.  In reality I have simply been working on getting my book, The Death Of Harold Hartline, in shape to be published.  I have been debating back and forth on how I would like to go about doing this.  My heart says that I should be patient and mail the manuscript out to publishing houses to see if anyone is interested in publishing it, but I know that this is a lengthy and sometimes disheartening process.  My head tells me something much different.  It tells me that I should continue with self-publication that I have started and get my book and my name out there for the world to read.  It tells me that this will start my book selling and will make me much more marketable as an author for any future novels I write.  The problem is that I'm not sure whether I should go with my heart or my head.  I have gotten advice from many sources, but there is no clear favorite.  So here I sit trying to make one of the bigger decisions of my career and I have to do it all on my own.  Heart or head? Which of you will get the upper hand? Only time will tell.
