Endurance inside of endurance. This evaded me for a long while. I believe the central concept here is that mindset of compound interest rates. At first, you're probably asking yourself, what the heck does this have to do with Judaism. The principle and correlation is pretty simple. Compound interest can work in your favor or against you. The interest accrued grows more and more rapidly as time passes. Why? Because the interest you earn is added to the principle that you are earning interest on. This is great if the interest you earn is profit, not so much if this is a loan that you have to repay. I believe this holds true in our lives for the torah that we practice. The more time and energy that we invest in developing our torah to be a light in our lives. The torah we practice in our lives can range from doing good deeds in your community to studying Torah. Certainly, if we don't practice torah in our lives we can't see the world improve. In order for the world to improve we must actively practice tikkun olam (repairing the world) and tzedek (justice). This means the responsibility is on us. When we take the first step we can then inspire others to join in and stand up for what is right. Then momentum builds and we see this compound interest take effect and we have started a movement.
