"For Its Own Sake" has many benefits

The last chapter of Pirkei Avot is about the glories of Torah study

"Rabbi Meir (Mai-eer) said, anyone who engages in Torah study for its own sake ('lishma') merits many things. Not only that, but the entire world is worthwhile for him alone. He is called 'friend' and 'beloved,' he loves G-d, he loves man, he brings joy to G-d, he brings joy to man. It (the Torah) clothes him in humility and fear. It enables him to be righteous, pious, upright, and faithful. It distances him from sin and brings him to merit. [Others] benefit from him advice and wisdom, understanding and strength, as it says, 'To me is advice and wisdom, I am understanding, and strength is mine' (Proverbs 8:14). It gives him kingship, dominion and analytical judgment. It reveals to him the secrets of the Torah. He becomes as an increasing stream and an unceasing river. He becomes modest, slow to anger, and forgiving of the wrongs done to him. It makes him great and exalted above all of creation."

The trick is to ignore the fact that there are all these benefits, and do it anyway.....
