Increments
Progress is not made in leaps. It is the accrual of many small increments. If you decide not to workout today it may seem like it doesn’t matter but that small piece and other such missing pieces may never let you make any significant growth.
Decrements
It is also true that you don’t spring backwards in leaps either. Retreats too are the accumulation of many decrements. If you decide to stop at the doughnut shop on the way home for just a doughnut, it may seem harmless at the time but that event and other such incidents add up and keep you from making improvement too.
