YouTube, good tool or not

[PersoniinTraining]

Hey, I am just starting to get into gaining bush craft skills and I have resorted to online to learn some skills. There are a few YouTube feeds that I have gone to and I have them below but my question is what looks legit and what should I avoid? Thank you so much for you inpu!
