What does it mean to get better sporadically and finally shine like the milky way?

"Getting better sporadically will eventually shine like the Milky Way" means that even if we only become excellent in some aspects, these excellent aspects can be pieced together like stars into a beautiful Milky Way. This sentence tells us, don't underestimate the change of small details, every little makes a mickle, and one day it will be brand-new. As long as we constantly improve ourselves, even if it is only a little insufficient, we can piece together the Milky Way.
