Ok, so there's no misunderstandings, i'm not reading challenged. I read every day, normal books i mean. But there just something about magic books that makes me lose interest easily. With all the "on your left second finger's first phalange" and "place the right third finger on the upper left corner" makes it harder to follow than a normal chapter book.
When you think of magic, what emotional quality would you categorize it with? More than likely - stimulating. When you watch a video, your brain is stimulated because it fits
your perception of what magic should be for you. When you read about magic, it isn't so much stimulating as it is instructional. By reading about it instead of watching it, the written words may not support your association that you have about it.
We take in and learn information in 3 primary ways - visual, auditory, and kinesthetic. Each one of these modes has its place, and, their own limitations. If I would tell you verbally, for example, how to do a sybil, we might be here for a while. If I tried to write down, in words, how to sing a solfège, again, it would not be as practical as hearing it.
By trying to learn something in a way that is not the most practical or efficient for you does not mean that it is impossible. It just makes it more difficult. You can, through perseverance, relearn how to learn magic from books. Its gonna take some time however. Be patient and work through it.
You may also be able to trick your mind a bit into learning magic more easily from books (no pun intended). Here are some ideas to try......
Read it aloud - read the effect that you want to learn word for word in your mind. Then read it out loud. By doing so, we gain auditory as well as visual stimulus.
Record it - take the instruction off the page by reading the effect out loud and recording it. Listen to it over and over. Add pauses where necessary. Listen to it when you are actually practicing it.
Get a loved one or friend to read it out loud and record them and try the same thing. This may induce receptivity to the instruction because of your association with that person.
Rewrite it - rewrite the effect in your own words so it is in a language that you can relate to. You may want to even try to record your rewritten instruction and listen to it while you practice.
Use books to back up your video instruction - if you are trying to learn something, find a vid that has the instruction. Also find several books that contain the same effect or move and use them in conjunction to support each other.
Lastly, add distractions. Something as simple as turning on the TV or radio for background noise can cause your mind to focus more on what you are trying to learn.
Hope this helps, best of luck.
