It's all subjective in that most people who want to draw or paint, likely have completely different ideas of what being good at that is.
"Drawing from the right side of the brain" is basically just a brain hack to allow a person to essentially trace what is in front of them. To some people that might be the goal. To make a reasonably accurate copy of what is in front of them. For others they may want to be able to draw an accurate picture of something from their head. Others may want to create wild stylistic abstractions. The original post referenced impressionism. In that case a more informed knowledge of color and composition might be more helpful.
Personally, as someone who has spent my entire life drawing(and a chunk of it painting) I cringe at that advice to learn from that book. I have read it and it will definitely help someone to render and accurate version of a photograph or object in front of them. But it really boils down to a shortcut as opposed to fundamental learning. Its like teaching math with just a series of steps to get the answer without teaching the underlying fundamentals of what is happening. In the short term you'll test well, but in the long term your growth will be stunted if you do not also learn the concepts involved.
Hope that is a bit more clarification. And with all that said, for some people that book might be wonderful. I do think it is well written and I did enjoy it and I imagine others will as well. Its a fun read and set of exercises. Just wanted to give you a bit more perspective on the opinions presented.
With that said, the general advice given in what you are replying to is way over the top. No one needs to spend 6 months drawing cones in space. That smells like your typical exaggerated internet advice that tends to prevent people from taking the first steps.
