Focus on Your Grateful list

From a Shiur by Rabbi Lazer Brody. "Kosher Humor".

One of the most powerful tools of the Yetzer Harah is to mach you focus on the bad instead of the good. Haman is a perfect example. He was not happy with everything that he had because Mordechai would not bow down to him.

That is why it is so impotant to focus on all of the things that we need to thank Hashem for.
