Boasting and Self Esteem

According to Ephesians 2, grace should lead to humility (boasting is excluded). But I (as a professing Christian) know that I am not humble.

I was born in the 1980s: my generation (some call us "millennials") suffers from an utter lack of humility. We were the unique snow flakes who could achieve anything, if we just gave it our all!

This excessive self-esteem means that we live lives of constant boasting. I'm afraid this proves that we have not understood (internalized?) the multi-faceted glories of God's Grace. That grace can only really be understood after a person internalizes the extent of his inadequacy and weakness and failure.
