First thing I learned? Thinking about piano is a form of practice. In my mind I saw myself performing the music. My mind sought solutions to tricky parts I saw coming. I was excited.
Second thing I learned? A firm date quickly eliminated procrastination.
Third thing? This was really exciting. As Los Angeles Clippers’ Doc Rivers said, "pressure is a privilege". This was real, this was difficult, but this was doable with focused effort and lots of practice.
Fourth thing? I started to listen in earnest to both professional recordings of my program and myself. Record, play, listen became my method.
I'd learned how to practice.
