Orchot Tzadikim
The modest person is happy with the portion that the Holy One, Blessed be He, has allotted him, whether it be great or small, as it is said: "Better is a little that the righteous has" (Ps. 37:16). And with his rejoicing in his portion he quiets his heart from the hustle-bustle of this world, and thus his heart is left open to search wisdom and to the service of the Holy One, Blessed be He.
