Just about every instrument I play I play "wrong" - not stopped me making a living from it!
In fact, in my recorder days I found that playing with wrong technique actually added something to what I was doing.
On my professional instrument being self taught, I do even the most basic thing wrong - when I started college and expected to be trashed for it, my teacher was, in this respect, even worse than I was. Didn't stop him from making a living from it either.
Doesn't matter how you do it, it's what comes out of the end that matters.
