Judson Brewer A simple way to break a bad habit (Adrià Castellví) 

Judson explain how break an habit whose is causing damage to us or simply is pernicious.

To break a bad habit we only need to keep doing that bad habit but doing something which wake up our curiosity.
Whereas we are watching or doing that thing our brain doesn't think about if smoking is bad for me or I can't leave smoking.

So when your attention is in other part your brain recibe the real feeling of that thing that we are doing wrong so our awareness understand that bad habit is bad because we feel it without think.

Finally if you have a bad habit try to do something which really interest you to keep focus whereas you are doing your bad habit then you will feel it without being aware and with time you will be able to stop it.
