Desires are the human’s gps – unfulfilled desires are the human’s frustrations – so save yourself a life of frustration; know this, which all of the true Jewish sages, from beginning of time to the greatest of them all, the Lubavitcher Rebbe, the Moshiach of our generation taught: – There is but a single good desire, to fulfill that which God requests of you!
