You may have the impression like your post is straight to the point and you have just given us the recipe for success, but I cannot fully agree with the content you provided.
I do not want to enter the depths of the ocean of dependence when it comes to making decisions, however I will give you a brief explanation of my point of view using your post as an example.
If our decisions were just products of some internal dialogue of our minds, your post would have been totally useless, without a chance to influence our way of thinking.
In my opinion, every decision we make is influenced by a set of variables, for example people or events that took place in our lifes - that is why different people have different perspectives.
It may be easy to blame idiots for being idiots, but every idiot is a product of circumstances and abilities and not just thier own, bizarre minds.
In other words, do not just judge people for thier choices, but help them to make the the good ones.
