When Hashem told Avraham: לֶׁךְ לְךָ to forsake his country and family, He explained that it was: ךָתְ בָ טוֹלְ וּ ךָתְ אָ נָ הַ לְ for his benefit (Rashi) since He would give him loads of money, children, Kavod, and a good name. What is the greatness of doing Ratzon Hashem when Hashem is saying that he will get so many benefits? The answer is that Avraham Avinu does everything only: כַאֲשֶׁר דִ בֶׁר אֵּלָיו ה ' because Hashem wants to make him great and rich, etc.
When you work on self-esteem, the point isn’t Davka that you need self-esteem in life in order to manage, etc. The main point is that Hashem wants us to have self-esteem, besides it being a healthy way to live. Such a person can suddenly be a big Anav when need be, since he is an Eved Hashem and he follows Hashem.
