Rabbi Joseph Telushkin’s The Book of Jewish Values (2011) cites advice from a 12th-century rabbinic text:
Set aside a sum of money that you will give away if you allow yourself to be angered. Be sure that the amount you designate is sufficient to force you to think twice before you lose your temper.
One way to kick a bad habit is to pledge to give money to a cause that you hate should you fail in your goal.
For instance, entrust a trusted friend (or the website StickK) with $200 and ask her to keep an eye on your goal to eat mindfully and lose weight. If you’re a lifelong Democrat, pledge to have your friend give away your $200 to the “Trump for President 2020” campaign should you fail to meet your predetermined criteria.
Idea for Impact: Try this negative reinforcement technique to inculcate some self-discipline. Make it motivating—designate to give away an amount that hurts or to a cause that you loathe!
