When R' Chaim Halperin Zatzal explained to me the importance of Limud HaMussar, he said that the Mussar you learn should hopefully fill up your mind with the proper thoughts, to combat all the unhealthy thoughts that circulate your mind all day. Bitachon vs. worries. The Chasidim say: “Think good and it will be good”.
It is worth your while to try to give time and effort to lift up your Mach'shavos. For example, think of becoming great, with ambitious thoughts of a beautiful future and friendly people, instead of loading your mind with shameful and avoidable cheap worry and depressive Mach'shavos. The more you try to alter your thoughts for positivism, Simcha, success, goodness, and feeling that everyone loves you, the more you become better.
מובא בהרבה ספרים בשם בעל צמח צדק מליובאוויטש: טראכט גוט, וועט זיין גוט ... ובספר עירין קדישין החדש מביא מהרה"ק מרוזין זי"ע ... שמחה גוררת שמחה ... לכן יש מאוד להשתדל אף בזמנים הקשים להתחזק באמונה ובטחון שיהיה עוד טוב, ועל ידי זה נעשה באמת טוב.
You can change your entire life, once you go on a campaign to upgrade the quality of your Mach'shavos. Everything you do is a reflection of your Mach'shavos. סוֹף מַ ע שֶֹ ה בְ מַ ח שָ בָ ה תְ חִ לָ ה The outcome takes the shape of the Mach'shava that preceded it. After a while, making believe you are a positive person with happy thoughts can conquer real depression. And after a while, Bitachon thoughts can bring Yeshuos.
