“I don’t learn amidst suffering,” the Rosh Yeshiva replied. “I learn amidst joy!”

Rav Nosson Tzvi Finkel refused to be enslaved by his debilitating disease:
“”Rav Nissan Kaplan related that after the Rosh Yeshiva passed away, he heard that a relative of the Rosh Yeshiva had testified that he never heard him complain about his disease. Rav Nissan was so surprised by this claim that he decided to verify it. When he visited Rav Nosson Tzvi’s children during the shivah, he asked each one whether they had ever heard Rav Nosson Tzvi complain – and each one said no!

Not only didn’t he complain, he didn’t even consider himself unfortunate. A student who had been struck by several tragedies in the span of a few months came to the Rosh Yeshiva for inspiration. “How does the Rosh Yeshiva learn amidst suffering?” he asked.
“I don’t learn amidst suffering,” the Rosh Yeshiva replied. “I learn amidst joy!”
