Why is it so easy to overestimate the importance of one defining moment and underestimate the value of making small improvements on a daily basis?

Because improving by 1% each day isn't particularly notable, sometimes it isn't even noticeable. But it can be far more meaningful, especially in the long run.

Here's how the math works out.

• If you can get 1% better each day for one year, you'll end up 37 times better by the time you're done.

• Conversely, if you get 1% worse each day for one year you’ll decline nearly down to zero.

What starts as a small win, or a minor setback accumulates into something much more.
