Know that there are people whose eyes are directed toward Hashem when it comes to major matters…but who do not remember Hashem in the small things. This is because the activity is trivial in their eyes and they are certain that they can succeed in it…Therefore, it says: “Know Him in all your ways” – large or small! 

Since all actions are dependent on Hashem, and all success comes about through His kindness, a person is obligated to remember Him in everything that he does. For if he succeeds in his activity and did not remember Hashem or look to Him for help, he is deficient in his Divine service.

~ Rabbeinu Yonah (1200-1263)
