If Christopher does not see this, I would post in his forum. I know he will have tutorials to put you on.
Personally, I stay in the key. I am not that good, never will be that good, but enjoy playing with others. So 1st question for me is "what key are we in" and I stay in that lane. But you sound more ambitious than me so whatever Christopher suggest will help with effort.
This year the diet is definitely gonna stick!
