Achievement vs Success

I have just finished the book, Start With Why, by Simon Sinek. He offers the definition of achievement as a goal that can be measured and seen very easily by others.  You can describe it, see it, and you can be rewarded because of it.  While success is a feeling, a state of being.  Not able to be measured with “data.”  

These two words would seem to go hand in hand but not always.  Many people will achieve a great deal in their lifetime but will never feel successful.  Where others will achieve no mentionable awards, but will smile daily filled with rich success. 

So, why would our nation pass the Every Student Succeeds Act when success cannot be measured with “data” and 99% of public education is measured with “data?”
