I'm starting to see benefits in my hands after a week now since returning from drum camp - feeling reinvigorated after being exposed to so much talent over 4 days! There's enough stuff to work on for an 8-hour day and I'm inbetween contracts so I'm going to oblige the opportunity LOL.For me, it's two things: Whenever I can feel myself improving in real time, like if I have a particularly good practice day I might think to myself "after today, I'm a ~2% better drummer than I was yesterday," and having a good idea of where you'll be in a few months time, since it gives you something to look forward to and even fantasize about.
Dave Weckl noticed an issue in my trad hand at the kit, and so I'm trying a slightly raised snare to fix that. That's helped me have more control. I'm also using Weckl's middle finger fulcrum - I'm not sure why but that fulcrum allows playing on slightly higher surface (eg a slightly raised snare). But the middle finger fulcrum creates an issue transitioning to Todd Sucherman's grip for ride playing. Weckl showed me he can make the transition so I know not to give up on it. But he didn't necessarily go over HOW he did it. I guess I can figure it out LOL.
