This theory and academic prep that you dismiss is actually pretty damned important. It lays the foundation upon which the experience becomes valuable. What you've suggested is taking the lazy way out on the premise that you don't really need to understand any of it as long as you can muddle through doing enough of it. It is not very good advice.
I do agree that experience is important but experience on top of knowledge is much more valuable.
