Here’s how I know my guitar is going somewhere. On top of learning the barre patterns easily, I have now actually dropped a glass of cold water and broke it. My fingers have have callused tips which feels little and has little traction. I used to hold my glasses by the tip of two or three fingers lightly. Now I have to hold mh glasses like a bloke drinking beer. Total grip.
I am not very keen on chord strumming because I prefer very clear single note sounds but it is more acceptable now using a pick. My teacher now emphasizes quick and efficient chord changing.
For my drums I am learning 16th note patterns. Really loud. I put on ear muffs.
For my ice skating, I was having a very hard time with the Waltz Jump just a simple change direction jump. I was concentrating so hard that I barked at any one that broke it.
I did get it finally.
