Interesting you are learning notation. I've been playing 30 years semi pro and thought I'd try it. Very hard ... maybe easier when younger, I'm self taught and had no music at school (unfortunately). I thought it may help get more gigs but it doesn't unless you do orchestra pit type work, even then the good sight readers are few. Fact is its tough on guitar, up/down as well as left/right unlike keyboards (they got it made!). Don't mean to discourage you but I abandoned it just because I have no need ... and I discovered feel and technique kind of take over.
Having said that I take my hat off to you! Good luck ...
