This is applicable to your kettle or your colleague.
I believe that we tend to more easily notice things when they are different or wrong.
While cycling, I only pause to think about my gears when they are clicking or not shifting correctly.
At work, the colleagues who need a lot of support or whose work regularly misses the mark occupy much more headspace than those who work independently and consistently do a good job.
When pouring hot water from a poorly designed kettle, I pay careful attention to ensure that I don’t spill water over myself or the table. When using a good quality kettle, the pouring process feels automatic.
Of course, there are exceptions where something (or someone) is truly remarkable and stands out because of its (their) quality. But generally, you notice the best, the least.
