u/the_guitarist_of_97

Hi. I am new in this sub and although I've been playing the guitar for nearly half a decade, I feel like I haven't improved as much as I should have. I am self-taught and I have some questions that I would like answered please,

1. What does the optimal practice session look like?
2. How to learn to read sheet music?
3. Can you suggest some intermediate level pieces to learn and learn from?

Thanks in advance.
