EMUUUUUUNNNNAAAHH!!! What a concept. WOWWW.
I heard most of the following ideas from a fantastic & inspiring shiur by Rabbi Dovid Goldwasser.
Chazal teach us that Shamai would go out daily and seek something nice for Shabbat. He would find a nice object, like a fruit or vegetable, and say "l'kavod Shabbat" & set it aside. Then the next day, he would go out and when he would find something even nicer than what he found during the previous day, he would say "l'kavod Shabbat." And that was one of his daily goals: find something nice for Shabbat.
Hillel, on the other hand, would go out on EREV SHABBAT and simply have emunah that he would find something l'kavod Shabbat. And he would find something every week.
So, who had a higher level of emunah?
THEY BOTH HAD EMUNAH!
So should an individual wait to see if (s)he finds something better or take the good that he finds immediately when he finds it? Should a person wait until the last minute? What if he won't find what he's looking for?
The answer is EMUNAH!
There's a quote from Tehillim => "they trusted HaShem, and HaShem made sure they weren't embarrassed."
Chazal teach us => "the tzaddik decrees and HaKadosh Baruch Hu fulfills!"
A person has to trust in HaShem and know that HaShem is "kol yachol." He can give anything to anybody. Nothing is beyond HaKadosh Baruch Hu; He has no limits. HaShem has the ability to give us all that we want. There is NOTHING that can't happen. A person should fill his heart with emunah.
One of the three questions a person is asked when he goes to Shamayim is: "did you deal "b'emunah?"
In this context, "b'emunah" is usually defined as business/dealings. Was the person honest in business? Did he cheat? Did he lie to his customers, to his shidduch prospects, etc.
However, there's another way to intrepret "b'emunah." LITERALLY - did you deal with YOUR faith?
Did you leave your emunah the way you got it in 2nd grade, or did you try to make it deeper? Did you try to grow? Did you try to learn about wha ta person should believe? Did you try to work on your middot and hashkafah and know that everything in our lives is Hashgacha Pratit?
The reason we don't know the reasoning for everything is in order to BUILD our emunah! If we knew the reasons for everything, then we would be HaShem. He's the only One Who knows!
Each individual is a ben yechidi or bat yechida (only child) of HaShem. There is NOTHING that is impossible for Him, and therefore, a person should always speak and pray to HaShem. Even for "minute" things -- because there is nothing that we can accomplish without His help!
A person should tell HaShem the following: "this is what I'm asking for. If it's good for me, please make it happen. If not, then please don't let it happen."
And if you didn't get it, then that means it wasn't right for you at the moment. A person with big emunah knows that what happens right now or doesn't happen is hashgacha.
Chovot Halevavot teaches us that the more a person can trust in HaShem, the more HaShem will protect him.
It behooves every individual to call out to HaShem and say "HaShem, You're my Father in Heaven! There's no one ELSE who can help me! It's not that I have plans A, B, C, and D. I only have plan A - HaShem! I am completely dependent on You, HaShem!"
If one approaches life with that outlook, (s)he will notice tremendous Hashgacha Pratit in life.
You have unlimited potential once you know that your strength comes from your connection with your Creator.
