Rebbe Nachman said that it is impossible for any human to fulfill one’s obligations in serving G-d perfectly. “G-d doesn’t demand the impossible from man” (Avoda Zora 3), “nor was the Torah given to the angels” (Kidushin 74). The Torah wasn’t meant to be harsh. About people who are too careful and add extra restrictions, the Torah says (Vayikra 18), “you shall live with them,” not “you shall die with them.” (see Mesechta Yoma 85a).
The commandments of G-d were made to bring happiness and joy into our hearts. This happiness can only be obtained through serving G-d with simplicity without adding extra restrictions that G-d does not ask of us at all. Truly one should throw away all the preconceived notions and assumptions and worship G-d in purity and simplicity.

Everyone must know that the essence of Divine service is to serve HaShem in truth. At every moment, examine and investigate all of one’s actions, even the good things and mitzvot that one does. If one finds in them (G-d forbid) any mixture of intent, pointing in any other direction (G-d forbid), or whether it be enjoyable, to the honor of oneself; we see that (such a one’s) intent of Divine service is not for the sake of HaShem’s holy, honorable, and awesome Name. All such a one’s actions are not for the sake of HaShem alone, in truth, and with a pure heart.
