Learning notes on the neck, scales. This book teaches a good system for learning the notes in the start, the CAGED system:

I'm currently working through it.

If you're looking for a book, I just got this one off Amazon: https://www.amazon.com/dp1480170496/ref=cm_sw_r_cp_apap_wNBQhwyWhoUZR
It's already helped me massively with soloing. It teaches you everything you need to know about the CAGED system and helps you master the fretboard. You just have to sit down and work through each chapter in order, don't skip around. After a few days, you won't dread practicing anymore. Also, don't force yourself to practice. Practicing everyday won't get you anywhere if you don't know what you're doing. Hope this helps!

From a recommendation by this sub, I've been learning lead blues guitar from a book called "Blues You Can Use". I can't recommend the author and book enough. He also has other books in the series, but I'd start with this one. Then, if you get through his works and still want some more work in the blues vein, the author Joseph Alexander wrote some great stuff, like The Complete Guide to Playing Blues Guitar.

After that, I recommend using a few books on the "CAGED" system of learning scales/chords/patterns. In particular, some that have helped me are Joseph Alexander's The CAGED System and also Fretboard Logic.

Then, if your head hasn't already exploded, use Justin Guitar.

Good luck!
