it has been said that the devil’s in the details.
this is what wikipedia has to say about that idiom:
“The devil is in the detail” is an idiom that refers to a catch or mysterious element hidden in the details,[1] meaning that something might seem simple at a first look but will take more time and effort to complete than expected [2] and derives from the earlier phrase, “God is in the detail” expressing the idea that whatever one does should be done thoroughly; i.e. details are important.[1]
What areas of your life could benefit from added attention, a more thorough examination, or a little extra effort? Take a moment today to reflect, slow down, and even if you do nothing different, appreciate the mysterious and hidden elements that surround you.
