The bigger constructs are made out of these smaller pieces. Focusing on just the high level abstractions will end up with your application being difficult to fix when something lower level breaks and focusing on just the lower level code will cause your application to end up unscaleable or refactorable because of poor design. It's a question of trade offs but you cant entirely ignore one or the other
