I don't know about straight quantity. There's definitely a balance. For example: my roommate and I both write songs in our free time. He goes for quantity (around 6 songs a month), me quality (1-ish song a month). I'll spend a week just trying to get a transition to a chorus or bridge. His songs often don't even have choruses or bridges. It would drive me crazy having a bunch of half-baked songs (or stories) that are almost there but are missing the next step. At some point you will have to put the hammer down and think "hey this idea is strong and deserves a strong conclusion/climax/chorus/whatever art form" rather than quickly moving on. However if you're just starting out, significantly lean quantity as your earliest works aren't likely worth the time.
