Dear team and members

I have been working through fundamentals 1 and learning to change from Am to Em the way Lisa shows us but I unknowingly started doing a different way and gone back to the way Lisa shows us however finding it difficult getting my hand position correct .

Without any disrespect intended if the other way for me seems to work better for me is it ok to stick to that if it works or is it best to stick to what we have been shown ? thanks
