I am new to skating because the amount that I skated as a child was really minimal, I only got to Beta level and then went on to other hobbies so I am not nearly as experienced as you are, but I may have a helpful pointer or two.
The first is that I keep a skating journal. The kind I have is actually a planner, but any notebook will do. My journal has my notes from lessons, individual pages for elements I am working on, and daily entries from what I worked on each time I skated and also any off ice training I do. If I have some sort of revelation that day I put a little exclamation point next to it and I also add that tip under the corresponding element section. My tips come from my coach, group lessons, my friends, or something I just realized about myself that makes the element easier or better. My journal also keeps track of my hours on the ice (you can use this to remind you that you will be due for a sharpening soon) and where I skated (public, adult coffee club or freestyle). I tend to work the hardest on freestyle, though I skate longer on the public sessions I do tend to socialize more (not a bad thing if I am getting some cardiac in)
So whether you keep an actual journal or not, make some goals for each skate (sounds like stopping is an issue now for instance). I have to actually force myself to practice elements that are harder or scary a certian number of laps or circles. It gives me something to aim for. I don't always reach the goal, but if I come close I am happy. Also, another thing I did was rather than just saying something like "practice stroking" I add things I want to work on specifically (holding extension, toe point, edges etc.) Especially with elements I am more comfortable with I try to be specific about what I am perfecting.
