Habits are the compound interest of self‐improvement. The same way that money multiplies through compound interest, the effects of your habits multiply as you repeat them. They seem to make little difference on any given day and yet the impact they deliver over the months and years can be enormous. It is only when looking back two, five, or perhaps ten years later that the value of good habits and the cost of bad ones becomes strikingly apparent.
This can be a difficult concept to appreciate in daily life. We often dismiss small changes because they don’t seem to matter very much in the moment. If you save a little money now, you’re still not a millionaire. If you go to the gym three days in a row, you’re still out of shape. If you study Mandarin for an hour tonight, you still haven’t learned the language. We make a few changes, but the results never seem to come quickly and so we slide back into our previous routines. Unfortunately, the slow pace of transformation also makes it easy to let a bad habit slide. If you eat an unhealthy meal today, the scale doesn’t move much. If you work late tonight and ignore your family, they will forgive you. If you procrastinate and put yourproject off until tomorrow, there will usually be time to finish it later. A single decision is easy to dismiss.
But when we repeat 1 percent errors, day after day, by replicating poor decisions, duplicating tiny mistakes, and rationalizing little excuses, our small choices compoundinto toxic results. It’s the accumulation of many missteps—1 percent decline here and there—that eventually leads to a problem.
