I see trust in God [Bitachon] as very important. That was ever since I saw the book Madragat HaAdam [of Navardok] at the Mir in NY. But how to implement trust in God in a practical sense has always been an issue for me. The way it worked at the Mir for other and for me was more or less to devote ourselves to learning Torah and taking it as a given that God would take care of everything else.. And that worked--for as long as I was there. But not so much since I left.

To me the issue seems always to be exactly how much effort do you do and how much do you cease efforts and trust in God. That may not tell you much about the inner heart, but it does relate to the practical aspect of trust.
