Musicians tend to be focused on details, pieces of a song or the whole song. If they let themselves, detail people can work 4 weeks on 2 measures of a song and never even get to the 150 measures they're not touching. Conversely, whole song people may get through 6 songs in the same period and not fix the many mistakes inside the songs they're covering. Check your natural inclinations and whichever one you are, watch out for your "temperamental" musical negatives.
