I am no great tzaddik nor is my story famous, but something happened to me just the other day which made a very deep impression on myself:
I woke up in the morning and it was pouring rain outside. Now, I have this weird thing that if it’s raining when I go to work, it puts me in a bad mood. I don’t care so much if it rains before or after, but I don’t like to walk to and from my car in the rain.
That said, I was not so pleased to see the rain coming down hard. (Don’t worry, I’m WORKING on my appreciation for rain!!)
Anyways, I said in my head, “Hashem, please make it stop raining by the time i want to leave the house! Please, pleaseeeeeee!!!!”
In the meantime, I davened and ate breakfast. Just as I was about to step out of my house, i saw that the SUN WAS OUT! I was stunned! I was not really expecting Hashem to make the rain stop for me. But the truth is, that He really cared. And He really wants me to be happy!
And then I stopped short with a realization: Something so petty, so unimportant, so not crucial. And G-d listened to my prayers.
The next time I spoke to Hashem, I spoke with a lot more faith, a lot more belief, and I made sure to also ask for things that really mattered.
And of course, He listened.
