I’ve always felt my right hand was the weak link and over 15 years i always come back to villa-lobos’ etude #1 and giuliani’s 120 right hand studies (sounds scary, but its really not) when i think i need a tune-up. Of the 120 i only focus on one or two sets of 5 per session, and either is great warm-up material too!
As has been already said, practice with a specific purpose is always far more productive than straight rippin through tunes (but we all need that from time to time just to keep us sane 🙂 so, good luck!
Oh and only practice as fast as you can play perfectly, i should know, im a poster boy for rushing things and thats often how bad habits creep in. Speed is something that kind of comes on its own as you become more comfortable with the tech/material.
It can be especially hard if you’ve come from a background of electric guitar (like me) to not want to immediatly achieve the same relative proficiency, but half learning proper technique will cause issues down the road when you move onto more advanced material.
I’ve never kept a journal but in retrospect i think it would have helped me quite a bit, causing me to divide up my practice time more efficiently. I guess its never too late to start either, good idea
