If you attempted to draw two parallel lines and one was off by a tenth of a degree, you probably wouldn't notice it within the first 10cm or maybe even the first meter.

But eventually maybe after a few miles you'd start to notice that something was off.

Little inconsistency and small flaws eventually amount to major problems.

Similarly, small delights, little surprises, small good deeds can add up to a lifetime of pleasant and memorable experiences.

It's all about the small details repeated consistently over a period of time.

Pay attention to the small details.
