It’s easy to let a bad habit slide. One unhealthy meal won’t much the scale much. One late night won’t hurt too much the next day. One cigarette won’t hurt you immediately. A single, poor decision is easy to dismiss.

It’s the repeated 1% errors and excuses that compound into toxic results.

From Atomic Habits:

The impact created by a change in your habits is similar to the effect of shifting the route of an airplane by just a few degrees. Imagine you are flying from Los Angeles to New York City. If a pilot leaving from LAX adjusts the headings just 3.5 degrees south, you will land in Washington, D.C., instead of New York. Such a small change is barely noticeable at takeoff – the nose of the airplane moves just a few feet – but when magnified across the entire United States, you end up hundreds of miles apart.

But luckily, the opposite is true. Consistent 1% improvements to your life can lead to a dramatic results in the future. The first step is not giving into that 1% concession.
