Cast My Soul

There are two distinct and seemingly contradictory approaches to what constitutes bitachon, complete trust in G-d. Approach A says that that bitachon is the confidence that Hashem will do for a person whatever he or she needs. Approach B say that bitachon has nothing to do with what an individual needs or desires. Indeed, it is the calm acceptance of whatever Hashem does, no matter how uncomfortable it might be. Which approach is right?
