In other words, we are always evolving. Life entails that we are always growing, so our evolution is inevitable. Of course, it's up to us not to accept things as they are, and not to stagnate.
Essentially, what we are striving for is a "conscious evolution."
As you said, we constantly evolve in unnoticed ways. We will never be able to notice every change in our being, every growth, but if we can get a clear glimpse of who and what and where we are, we can also focus on who and what we want to become, and where we want to go.
Onwards, my friend, and while we're evolving, let's also progress Full Steem Ahead.
