Negative Thoughts About Yourself May Be a Grave Sin

For many, many of us, any negative thoughts about ourselves should be like an Issur D'oraisa, since it’s the Yetzer Hara that loves putting you down; and your main reason you came to this world is Tikkun HaMiddos, and your main Midda Ra'ah is to always downgrade yourself. Every Chazal is Kodesh Kodoshim, and has its time and place. For so many of us, the #1 Chazal in our lives is : אַל תְהִי רָשָע בִפְנֵי עַצְמָךְ אבות ב יג Don’t consider yourself a Rasha, no matter how low you have fallen!
