You may contend that you can't break your bad habits because you are addicted to something.
Nobody is addicted to any bad habit.
It is impossible to be addicted, to be physiologically dependent and need anything, that is bad for you. To contend that you are addicted, implies that some external destructive stimulus is controlling you. You are irrationally assigning to something outside your body, pathological power over you. To contend that you are addicted to some bad thing, is to give yourself an excuse for your wrong belief, that you are unable to break a bad habit. To contend that you are addicted, gives you an alibi to rationalize, that you are unconsciously and compulsively devoted and obsessively dependent, upon some bad thing.
