imprisoned by routine
Jerry's problem is that he was ruled by fear. fear causes us to cling to a routine in order to maintain a sense of security. but a routine you cant escape becomes a prison.
Jerry's routine would have been perfectly fine so long as he could leave it and return to it freely. COURAGE COURAGE COURAGE! To come and go as you please.
great job, you've scincerly pointed out an enormous modern social problem: the wasteland. try reading Joseph Campbell, a professor of mythology, and an amazing story teller. his life's work can be summed up in the phrase "follow your bliss"
