do as i say, not as i do

I find people who are slaves to their own addictions telling people what to do extremely hypocritical.

I hate it when a person addicted to smoking tells a fat person to "control their diet" because apparently "it is not that hard to do so" or "it is unhealthy". Oh, so smoking healthy then? – Also, if it is not that hard to control diets, why don't I see you control yourself and quit smoking already?

This is the reason why I cannot take the advices of gym instructors who smoke / do drugs seriously.
"GET FIT, IT'S FOR YOU OWN GOOD"

Oh go fuck yourself, you liar, you hypocrite.
