Is there a good expression for chasing something insignificant while missing the bigger picture? I was thinking something remotely related to "penny wise, pound foolish" but not quite. More like not raising the bar high enough, or settle for less. Focusing on the insignificant, in comparison to what else is possible out there.
An attempt for a context example: when repairing one's house, they are obsessing about small details like painting the door or fixing a loose board, while ignoring the fact that the ceilig is about to collapse and would need to be fixed urgently (i.e. there's much more to gain there).
