I feel like i miss the boat or missing the even bigger one.

As i want to develop new skills on trading i would like to know more about trader sources. What sites they use or which news sources they follow. And is there any book e-book you can advice? Thank you all answers!
I think the easiest is a friend because we not only learn the theory but practice, if you do not have friends who can be spelled out in the great trading you can learn through youtube, book or e-book just is not enough I think you need also is learning by doing.
