<p>you cant teach yourself engineering, just as you cant teach yourself brain surgery. Certain engineering fields such as computer engineering or programming can be self taught, but those feilds are not however ‘real’ engineering. Mechanical, electrical, civil etc are Professional fields and you will never enter those fields ‘self taught’ there aint such thing. Watching videos on the internet will not make you an engineer, you need to get your 4 year degree and become licensed as a Professional Engineer which is a real engineer.</p>
