How much of our parnasa, income, is from G-d and how much from our own efforts? It reminds me of an old classic Peanuts cartoon. I can't find the actual cartoon to post, but here are the words:
Linus: "I'm afraid to look at it. Oh, I hope I got a good grade. Please, please, please let it be a good grade."
Charlie Brown says to him, “You should have done all that hoping and praying when you were studying for the test.”
Linus replies, with a look of disdain, "Hoping and praying should never be confused with studying."
Linus is right. But please remember that our success is a combination of our own efforts with whatever G-d wants to give us in This World, Olam HaZeh. Remember, our final accounting for reward and punishment are in the Next World, Olam HaBa.
