Novardok R' Yitzchok Orlansky Zatzal was once walking in the street, and he tripped and almost fell; but he caught himself before he could fall. He made a remark that the falling would have been Gevaldig for him, since it's Yissurim which has tremendous Kapara-value. People don't live with these thoughts, and it is a severe loss for them.
A Baal Mussar lives with Chazal, who say that every tiny inconvenience is real Yissurim and is a great Kapara. You need to thank Hashem for these ongoing tiny daily Yissurim, and then you Mamash lose your sins, and spare yourself more serious Yissurim, like a trip to the hospital, Chas V'shalom, and even from the worst Gehinom.
It is a Bracha to be forgetful, or to be delayed in traffic, or to have a person in your life who hurts you regularly. Such a person is: אֵׂ ינוֹ רוֹאֶּ ה פְ נֵׂ י גֵׂ הִׁ נוֹם not going to suffer in Gehinom, providing you always thank for those Yissurim. (Gemara).
Those who live with Chazal, like Novardokers did, are truly happy people; especially if they learned the appropriate Mussar and they keep repeating how: יִׁ סוּרִׁ ים מְ מַ רְ קִׁ ים Yissurim cleanse your soul from all your sins. (Gemara).
The rest of the world lets everything go over their heads. They lose tons, and they live an empty life compared to the real Baalei Mussar.
