Koheles Ecclesiastes 7:20-22
Man is not unfailingly good; through Teshuva perfection is achievable \u2022 Be judicious in what you take to heart \u2022 Don't indulge your slave, the evil inclination, as it is never appeased only emboldened to subjugate you \u2022 Don't feel crestfallen by criticism, it can often be a reflection of our own negative judgments of others
