One of the tricks of the Evil Inclination is to get a person to feel that he can not move, and thus feeling trapped the person easily succumbs R"L to bad things. This very feeling can and should be used for the good, and is really a door and gateway to holiness, as we know that before a person can enter the chambers of holiness he must traverse the chambers of exchange where everything is mixed up. Essentially when a person dies and his soul is freed to go up, his body is trapped 6 feet under, covered in dirt, grime, with worms and termites eating and completely consuming his body - you can't get more trapped than that. So when a person starts feeling the inclinations to give up, heeding the voices and demons persuading him that he can't move, he should turn the tables on these monsters and use this as a springboard to propel his soul up high and cling to the highest holiness.
