I can stumble through a tune now on the fiddle.
I take it to work with me. I don't always get the two scheduled breaks, I can't always practice on those breaks (sometimes I need to use the time to make a call or have a snack or something), but I still average fifteen minutes of practice every day.
Not a lot. But that's every weekday, plus I pick it up at least once on the weekend. And it adds up, bit by bit. Eventually even Diamond Mountain gets ground down.
Now all I need is more things with a good Bird Quotient. Unfortunately programming and writing don't make it. Fifteen minutes isn't even enough to figure out where you left off.
