Are lessons worth the money?

Lessons are worthwhile if you're a beginner to get the fundamentals right.
After that they're only worthwhile if you have to time and energy to practice what has been taught
If not then I don't see the benefit.
The odd lesson here and there, if things are going a bit wrong is fine but again, only if you listen and put into practice what is shown.

I'm a bad practicer at best, have never had a lesson and it's worked OK for me......
That's not to say that method will work for everyone...
