Although I'm not a great fan of quantity over quality it all comes down to your personal talents and possibilities. For some folk things are just right, others will turn their noses up at it. If all were perfect, there would have been no rock and roll, no blues, no folk and definitely no punk, only classical music.
You can go overboard looking for the perfect track, I have ruined more songs trying to meet the standards set by the pros than I care to remember.
Just like the patina on an old guitar, it's the imperfections that bring it to life. As Leonard Cohen so aptly put, "There are cracks in everything, that's how the light gets in."
