Last year, a certain yid was on death-row in Iran, Hashem yiracheim. One day, two Novardekors got together and proclaimed: "Aderaba! Vinahafoch hu! Asher yishltu hayihudim heima bisoneihem! Just the opposite! The 'Hamans' of the generation are going to get it!"
This was Friday. That Sunday came word of the mysterious helicopter crash that brought about singing and dancing in the streets all over the world...
Now we know who gets credit! And the more we focus on the miracles (and thank Hashem for them), the more we get.
The truth is that no one knows anything, what brought about what, only Hashem, who is anyways the One that does it all. However, a smart person goes around saying that I was the one who caused all the miracles (like by the "12-Day War"), with my davening and bitachon, for this way one is motivated to keep growing, and the sky is the limit! (And who knows, maybe it actually was your tefilos?). Chazal teach us hevi arum biyirah, be clever in your service of Hashem, and develop tricks that help you take over the world. And everyone will thank you later...
Be a tamim ("simple"-minded)!
