We Simply Don’t Appreciate Ourselves
I know several Chashuva Yidden and even Gedolei Torah who weren’t appreciated and didn’t “make it”. I’ve heard remarks like: “They don’t appreciate so-and-so”. I can say with Achrayus that this is virtually true about all of us (including our best), we simply don’t appreciate ourselves. The Yetzer Hara makes you focus on all kinds of sins and weaknesses. And there are hundreds and hundreds of Zechusim that people have, but it can mean almost nothing to them.
