Chazal tell us that those who rule over their Yetzer tell us the secret is to make a cheshbon. The Mesillas Yesharim expounds on the idea that this is the only way we can be successful, even if we do many things for our Avodas Hashem.
Some thoughts from Rav Moshe Shternbach about the importance of cheshbon, and how we are judged and written every night.
Have a good Shabbos
