So many people are prisioners of their own minds and habits

   So many people are prisoners of their own minds and habits.  
   Isn't it odd?  One would think people would be free --- free to 
   do anything --- but they are not.  They are slaves to their 
   desires, cravings, fears, habits, and mental tendencies.  Give 
   some examples. 

      - alcoholics
      - drug addicts
      - smokers
      - obese people
      - homosexuals
      - shy people 
      - people with inferiority complexes
      - people with phobias
      - people with mental disorders (paranoia, schizophrenia, 
          etc.)
