In Novardok and in Brisk they held that working on Bitachon is much better than actually getting what you want. The Alter Zatzal once cried when he got his desire, since now there is nothing sweeter and more delicious than being Osek (involved) in the Mitzva of Bitachon! Here is the story:
A Minyan of Novardokers (including the Alter) were once alone in a Bais HaBedidus (a sheltered house, sheltered from outside influences) for several days. They had no food, and were working on Bitachon that somehow Hashem would help them. Suddenly, a Jewish farmer happened to pass by and gave them bread. They were overjoyed, because they realized what a Ness this was. But the Alter said that he missed the tremendous closeness to Hashem he had, while they were working on Bitachon.
The true Bitachon is: ְמנוּ ַח ֶנ ת ֶפשׁ ַה בּוֹ ֵט ַח the calmness of the Baal Bitachon (using the words of Chovos Halvavos); the relaxing Geshmak of being Zoche to work on Bitachon.
