The factors upon which a man’s breakthrough in life depends
Getting accustomed to the situation.
Very often people get used to their situations and will not try to do anything to change their state of being. This lame guy got used to sitting on the same spot for 40 years and probably did not believe in any change any more.
I read this story about one dog that has been tied to a pillar. Each time the dog tried to run, she felt the restriction. After several attempts the dog got used to its position. And even after this dog was untied, it still continued to move around only within the habitual radius.
