Instruction often comes in the form of rebuke/reproof. Being willing to listen to it is the key to being wise. The rebuke/reproof has to wise of course otherwise it is mean cruel for it's own sake. Parents for instance need to be as wise or wiser than their own fatherly instruction, which many times means being wise enough to listen to our Father's rebuke as well.
If our hope is in something that has no possibility of coming forth or is not in the will of God or is not pursued in a manner pleasing to God or we never diligently pursued it the heart will remain sick. One must be honest about what is deferring the hope. Who, what, when, where, how, to what extent and to whose glory seem to be the appropriate questions.
