LOA is one of those things that just baffles me as to why people buy into it. It literally amounts to nothing more substantial than, "Close your eyes, cross your fingers, and wish on a star, then alllllll your dreams will come truuuuuue!" It survives on the average person's ignorance of advanced science and their tendency to assume that someone using big words and "sciencey-sounding" concepts must know what they're talking about.
The wife from the second example – she does it as well: her thoughts are gaining strength the more she nurtures them, making her feel even more insecure, making her become less and less desirable to her husband; and when he goes, if she doesn’t snap out of it, she could eventually become a vortex of despair, attracting more and more bad things to her life.
You claim that "positive thoughts always resulting in positive things" is not the basis of the LOA. In part you are correct. The foundational basis in science, as I alluded to in the article was that thought stuff particles travel through ether (not air) and interact with formless stuff to create whatever it is that you are thinking about. This was how "the law" started.
And NOT EVERYTHING is your fault. As a psychologist, you should know that we have 65000 thoughts a day and most of them are not conscious. In that case how are you supposed to know that you were thinking so subconsciously? (SUBCONSCIOUS thoughts matter too!). In fact, LoA users use their subconscious mind as a great asset. The truth about the law of attraction is actually simple.
Unfortunately, this author has an extremely superficial understanding of the LOA. While he may claim to have read all of the books, he clearly didn't understand them. He really isn't to blame as unfortunately many of the books written on the LOA are written by people that do not fully understand it themselves. The statement that positive thoughts always bring positive things is a faulty premise that is not at the basis of the LOA.
Have a strong desire. Now we know where we’re going and we need something that energizes the vision. If you’re flying to Hawaii, you know that plane needs fuel to get there. The same works for your vision, you need the right fuel so you can manifest it. Have a vision that moves you and each time you think about it, you feel lighter and joyful. These are the emotions that will get you where you want to go. Dare to dream and think big, it will help you to literally energize your vision.
