Yay on the derploma!
Just wanted to reply to what you said about not hitting anything new…
You shouldn't hit a new trick every session. You should actually aim to NOT hit a new trick every session. This isn't Pokemon, it's footbag. We don't have to catch' em all
Instead of trying to hit a new trick every session, try to beat a personal record, or try to hit a new link both sides or a new drill (for this to really pay off, try to hit the new link 5x both sides and the new drill about 3 times). I usually try to hit a new trick every now and then, when I start to feel stale or when I think I've practiced 2 components a lot recently and the new trick with both components should be easily hit within 3-5 tries. If you can't hit something within 10 tries, it's a great idea to just give up on it, and drill it's more basic components. However, use that trick that you can't hit as a sort of "progress marker", so you can see how hard it was that day, then after drilling the components of the trick separately, you'll hit it and you can see your progression that way. Sorry for rambling about this.. just figured I'd post some thoughts on it.
Try this approach. I think it will work out much better for you.
