Query: Why did I wait so long?

I have been meaning to try something that would improve my reading speed/comprehension and am I glad that I did! I purchased this book, read it, and did the exercises. My reading speed went up from 239 to 385 words per minute. And my comprehension got better. I wish I had done this course many years ago since it was so easy and straightforward.
