When you have so little to be personally proud of.....
Many JWs that are pioneering or reaching out for more privileges have minimum education, minimum wage jobs, no hobbies, no sports, no outside-the-cult interests, no individuality or outlet for self-expression.
Let's face it JW life is all about denying self and never doing enough so their (meaningless in the real world) titles become hugely important to them. They overcompensate for deep down feeling like a worthless piece of crap by bragging about their JW credentials and pedigree.
Sick, sad little cults like WT wield a stick and hold out a carrot - the titles and accompanying bragging rights are part of the "carrot" program.
