4) I work on more difficult songs playing by ear. Which is part of my ear and muscle memory
training. Sometimes I try to just play straight through the songs from beginning to end. Sometimes I play trouble spots at multiple speeds.
5) I work on sight reading music if I have more time. That is an advantage we now have in this day and age with smartphones. I almost always have my smartphone on me as well as my Coda EDC flute.
Well there you have it. The basics of my practice sessions. Obviously this is more or less dependent on how much time I have to practice. Also take time to watch and listen to other musicians and music.
P.S. Practice Practice Practice
