If you understand compounding you would understand today's quote of the day:
1% better everyday can lead to big changes
There is this way of thinking about comparing oneself with their former self the days past to see if they are better. In other words self improvement whether gradual or significant it is still going to add up in the long run. That is one example of what today's quote is describing.
There is also the thought of compounding an asset or investment over the long run. Imagine earning 1% yield on my income on a daily basis, that would mean 365% in a year. For ten years that is 3,650%. Wow rich baby rich! The small gains add up in the long run and that is the magic of compounding.
