It is easier to prevent bad habits than to break them.
Benjamin Franklin
First let us define a bad habit as a habit you would like to break. Most ‘bad’ habits are just things we have labelled as bad and aren’t morally or ethically wrong. Just like most weeds have beneficial properties and are only weeds because they are growing where we don’t want them to grow.
So with that definition in mind, are habits easier to prevent than to break? Not according to science. Science says that it takes 30 days to build a habit and 7 days to break one. I guess that means the real question is, do you want to break it?
