Keep in mind too, our failures serve to teach us, and usually teach us more than our successes do. What we may perceive as a failure is also an opportunity for someone else to rise to the occasion and perform a mitzvah, or mitzvot. Do not begrudge someone their joyous performance of mitzvot. Sometimes, perhaps even more often then you may think, what we consider our failures were blessings in disguise for ourselves, or others, or everyone. Abraham did not change the world just because he himself changed, and followed his own destiny. He changed the world through his giving others opportunities to rise to their own greatness.
