Based on the writings of Rav Chaim Cohen, the Chalban, Tallelei Chaim, Sefer Bereishis, P. 541. Why not just forget about asking for anything and let Hashem decide and do whatever is best for me? What Hashem does is HIS business, I have to do my part. Too much humility is also not good. Humility in greatness, Avraham Avinu, Moshe Rabbeinu and R' Moshe Feinstein. A person doesn't need to "hold from himself" yet clearly understand his task and abilities. From humility to emes (truth) to hakaras hatov (gratitude). Recognizing that ones capabilities (kochos) were given to us by Hashem - that is humility, and it leads to gratitude. If everything is from Hashem, then it becomes clear to me that I am nothing; however, I am STILL one of Hashem's creations, therefore I am of worth, but I am not the initial cause of that worth. When greatness misfires and causes pride. The closer we are to Hashem, and the more brachos ([outpouring of] blessings) we receive, the more we are humble. The malach (angel), who is so close to Hashem, recognizes more than anybody else that it's not about him.
