Musar su Salmi 68:20

A person must take all these words to heart and recall at all times that Hashem’s “eyes” roam about the entire world continually. Here is a valuable principle to adopt: Do not anything in private that you would be ashamed to do in public! Hashem is a merciful and gracious God. When He sees that your intentions are for the sake of Heaven and that you wish to adhere to the path of virtue and integrity He will send His angel before you to save you from all sin and from every evil matter. And if you do suffer any harm or mishap, accept it with love, as I have already discussed at length (Chapter 31). If you are successful in your business ventures so that your income is generous, do not say, “My cleverness has stood me in good stead.” For one must know that, “Bread is not to the wise” (Koheles 9:1). Rather it is all a “gift from God” (ibid. 5:18). Therefore give praise and acknowledgement to the Holy One Blessed is He for everything. For the Sages comment on the verse, “Blessed is Hashem day by day” (Tehillim 68:20), that one must give praise and acknowledgement to God every day for whatever He metes out, whether for good or for evil, Heaven forbid (Berachos 40a). On this account Hashem will bless you from Tziyon and you will succeed and flourish in all your endeavors, Amein.
