I can see the big 50 coming closer with big steps.
I started playing/learning classical guitar with age 14 for a couple of years (6 or 7 don't know exactly).
Certain circumstances made me quit playing. Now I started again learning guitar with the help of guitar tricks on a different guitar.
Not my classical guitar is in focus. I switched over to an electrical guitar that I took over from a family member.
So am I a beginner? Yes and no. To my surprise I know how to play the old classical songs and exercises (in theory), but my fingers are out of practice and not even used to play. Finger strength and dexterity, hhmm, gone.
That is even a hard to accept fact and to be patient with myself.
So I started from the absolut beginning with the lessons here. Ouch, my fingertipps are not used to steel strings. Strumming and picking with a pick is new to me too.
Lot of things to (re)learn. But I'm into it and practicing every second day, starting with tuning and warm up (4 finger spiderlegs).
The days inbetween I'm memorizing the things I've learned so far or watch the theoretical lessons.
A few times a day I perform the stretching exercises for fingers and hand.
But a most important thing to mention is: I have a lot of fun.
