People asked R’ Shimon Yaroslover zt’l,

“How did you merit to live such a long life?”

He replied, “It’s because I never asked questions.  When a person asks questions about how Hashem leads the world, Heaven replies, ‘Come up to Heaven. From up here you will see that everything is for the good.’ I never ask questions, so I wasn’t called to Shomayim to receive answers.”
