Well you could argue that that's exactly what addictions are, weakness of the mind or atleast a part of it. Can i ask, do you have history with addiction of any kind? Because i have to disagree with you hard on quitting is easy. Addiction to narcotics or alcohol is almost always because of depression, trauma, or ptsd etc. and the person uses narcotics to numb themselves, and to function. So its not easy to quit, because without it you fall in to darkness. It's actually just the same as saying "just smile and get over it" to a depressed person, because thats usually what an addict is: depressed. (Or something like that).
And yeah the pressures and standards of modern day life create these problems.
I'm not gonna call addiction a weakness of the mind.
If a person is going through depression or addiction or both, they don't just label themselves with a disease or at least they shouldn't.
Sit down and take note of what is causing the desire to escape or what is causing depression.
First thing I tell people, imagine you're filthy rich, you live in a paradise, you have all your needs taken care of, you will never have to put up with shit again in life, you are secure.
Are you still depressed, is there still something that drives you to want to self destruct, or do you suddenly feel a great weight off your shoulders knowing that you live on fantasy island and everything is gonna be fantastic from here on out.
So I ask, is the drug addiction and depression caused by your life situation, the people that fuck with you, the society that fucks with you, the society that taught you to hate yourself and look down on yourself because you don't measure up to others?
Now we go back to my good friend Diogenes, the homeless ancient Greek philosopher madman that was content to own nothing, live in a barrel and survive only by his wits, as he cynically made fun of the pursuits of people around him as they furiously chased the cheddar, while he whipped his cock out in public and began to masturbate.
It's all a state of mind and if your mind is caught up in the world then naturally you could be one of the unlucky millions who are crushed by expectation that is forced on all of us in or that we justify our existence in the eyes of others.
The objective for anyone suffering this plight is to free their mind from the bondage they carry thanks to years of programming you have received. As Master Yoda taught...."you must unlearn what you have learned". A state that is thought-free, alert, attentive, but clings to no content. In other words your true nature, before huge piles of bullshit was piled on.
