How did you learn Blender video editor and nodes.

I want to know how you learned blender video editor and nodes by just reading tutorials online.Are the tutorials hard?

I did a few video tutorials, they helped a lot, here are a couple of channels I found very useful.

Same way you would learn anything, do a tutorial over and over until you can get the end result from scratch without having to go back to the tutorial.

By doing.
I did not follow tutorials. I simply started.
