Rabbi Simcha Zissel of Kelm constantly stressed the importance of working on peace of mind. He suggested the following exercises:

- When you wish to tell someone a piece of news, wait at least fifteen minutes until you tell it to someone else. - When someone asks you for advice, don't give an immediate reply. Think over your response for at least five minutes. - Before you speak to someone, think first about your goals. - Think of how you will say something before you say it.
