You need focus on other parts though, you can have the most beautiful codebase with the most efficient algorithms, the highest coverage and the most extensible yet simple and elegant architecture but if you're not solving the business problems someone's going to eat your lunch with a hacked together excel sheet. The other view I have on this is around trust. Do I need to "focus" on the code if I have people on the team whose job that is? At what level? At a more senior position I shouldn't be looking into the small parts, the more effective use of time is ensuring the larger components are going in the right direction and/or we're not spending time on parts expected to be unused due to a strategic shift coming in. Maybe it's more important to focus on documentation right now, or perhaps it's important to get people working on different things because everyone's fixed on their small problem and not understanding the integration issues we have. Code is important, but it's important for a reason. Create your artistically beautiful perfect codebase when that's the goal perhaps as a personal project, but businesses have different goals and its focus should be on achieving those. "Focus" or attention I guess, is a limited resource. Spending it on one thing is not spending it on another. Balance is needed - 0% interest in the code is a big issue, but so is 100%.
