You hear that from a lot of great players. I always thought it was hyperbole, until now.
I’ve been practicing a lot lately, try to get things “just right.” This week I noticed how much it hurt to make chords. then I saw the blood on my fingertips.
“Wa-hoo!” I thought. “I’m gonna be a star! I practiced til my fingers bled!”
When I proudly announced this to my wife, she said “Use hand lotion.” Your skin is dried & cracked from the dry winter air. Use hand lotion."
There is just no impressing some people.
(Especially the ones that are right.)
