Reference for Pirkei Avot 2:12

רַבִּי יוֹסֵי אוֹמֵר, יְהִי מָמוֹן חֲבֵרְךָ חָבִיב עָלֶיךָ כְּשֶׁלָּךְ, וְהַתְקֵן עַצְמְךָ לִלְמֹד תּוֹרָה, שֶׁאֵינָהּ יְרֻשָּׁה לָךְ. וְכָל מַעֲשֶׂיךָ יִהְיוּ לְשֵׁם שָׁמָיִם:

R. Yossi says: Let your friend's wealth be as dear to you as yours. And prepare yourself to study Torah. [Do not say: Since my father is a sage and my grandfather is a sage, "Torah returns to its inn" and I need not pursue it], for it is not an inheritance to you. And let all of your deeds be for the sake of Heaven. [Even when you engage in eating, drinking, and marital relations, do not be motivated by bodily pleasure, but by a desire to be healthy to do the will of your Master.]
