Don’t take every plan as normal meaning it’s not a must trading or investing works perfectly fine after reading different books. I often prefer reading rather than watching YouTube videos, basically those videos might stand as an inspiration depending on how well you understand the field. Why not try researching books like I came across this book called the intelligent investor while researching although I have not make up time to read also make research on beginners guide.
All people are different, for some the best way will be books, for others it will be YouTube videos, and for others some other way, like working with another person who can point out the mistakes being made. After all, the fact that you are studying something does not mean that you will start to apply it correctly, mistakes will be made in any case, and it is good if these mistakes can be seen from the very beginning, and not when they lead to losses. So there are many ways, and which one to choose will depend on each person.
