Sean Carroll, calculus as a set of tools, chores

In his fascinating book From Eternity To Here Sean Carroll discusses time and its theories. I'm done with the book and am reviewing the footnotes and found this little gem:

"calculus provides exactly the right set of mathematical tools to make sense of “chugging forward one moment at a time” when time itself is continuous."

It struck me that perhaps calculus then can make sense of my entire life, since chugging forward one moment at a time is generally how I try to live. 

Who would ever think it? 

Maybe my children are right. It's time for me to take on calculus. :)
