Just do it. It's so easy to let the emotional part take over. Be a business person. Polish up the product and put it out there. Produce the next product. I think it's important to remember to keep artist-you and business-you straight, and know when artist-you needs to go sit down and have a glass of wine or something and let business-you take over and put a stop to the, well, feeling all the time. Believe in your story. Sell it.
