 After the first and second movement, for the first time we feel complete joy and this movement is exuding that from the very beginning. I think the most important tip I would have is to prepare for the right tempo. There's a very big danger of starting too fast and this is a movement where it can get very quickly out of control so it makes sense to give yourself or almost self-conducting your mind two bars before actually starting to make sure that you're at a comfortable tempo. One thing I would also do in the second bar is to give myself this impulse on the second beat. This is first of all to ensure that one doesn't rush and also to give yourself another reason to be very stable and you can do that by giving an audible breath or at least by feeling this beat with the rest of your body and that can be repeated throughout the rest of the movement.
