I can relate to your frustration. I often am irritated by poor instructions even in videos. It is important to understand all the terminology, symbols, basic folds, and to make precise as possible folds. I like videos that animate the folds forward and backward for each step.
With video instructions, the stop and rewind can be done repeatedly. Watching multiple times has been the only way I got through some projects. I also have thought that it would be most helpful to be shown live. It would have saved me hours of time if I were learning from a live person.
One way I have learned more complicated projects is that when I get to a part I am unsure of is to fold it with my best guess and, I soon find out if it works or not. If not I refold to my problem spot and repeat the process of using my best guess until I get it right. Sometimes with the same piece of paper but, it is usually best to use a fresh piece of paper. The more projects you complete though the less you will find yourself having wrong guesses. I say if you want to run but have barely walked then go ahead and try running because it does not hurt anything but, keep up the walking. Before you know it, you will be able to run with no problem
