THEORU

I am new here and really happy to find this forum. I have a question tho so I wasted almost a 2 year watching RSD videos. All I watched and heard was wrong? Like all the theorical shit ive learned from them wrong? Bc if it is i feel so sorry for myself and I wanna know how am I gonna learn the real info and tech. I never paid them bc i got no money anyway but i invested my time
