I think, that it's almost the best way, cause you can't achieve anything, if you don't like it. And that's the way I've come through.

I'm not sure I'd call it a "method" of learning guitar, more something you do as a part of learning and putting into practice what you have learnt.

To me, a method of learning is things like having lessons, reading a teach yourself book, etc

Yes, absolutely. IMO a very good way to learn technique is to try and do exact copies of someone else's playing. However, I do not advocate playing exact copies unless you are in a tribute band, they are a learning tool, not an end in themselves.
