Most who avoid quitting their jobs entertain the thought that their course will improve with time or increases in income. This seems valid and is a tempting hallucination when a job is boring or uninspiring instead of pure hell. Pure hell forces action, but anything less can be endured with enough clever rationalization. Do you really think it will improve or is it wishful thinking and an excuse for inaction? If you were confident in improvement, would you really be questioning things so? Generally not. This is fear of the unknown disguised as optimism. Are you better off than you were one year ago, one month ago, or one week ago?
