I think you should have fun, yes, but also keep trying to be precise. Do rectangular patterns, with upwinds, cross winds, down winds base & final approaches, have square corners in the rectangles. Be profficient and comfortable at flying both right hand and left hand patterns. Flying figure eights which meet precisely in the middle and stay at the same altitude, with equal banking and sized circles, is great practice. T&Gs until you really feel at home with the plane. Bust all this up with some just plain ringing it out fun. Then try to do three equally sized loops that don't drift off one way or the other. Do insides and outside loops, fly pattern's inverted and figure eights inverted. I find that loops do more to tell me if my plane is trimmed and balanced right, then any other manuver.

In your turns, try to make sure the fuselage is parallel to the ground, not diving or climbing. In level flight attempt to maintain a wings level attitude. Developing a sense of these two things being right will make you much more precise in your flying and is a problem you can work on the rest of your flying life. People don't really pay enough attention to these two simple things. However, knowing when you've got them right allows you a platform for jumping off to the rest of the manuvers. Or, you can be a good flyer and have fun, without paying attention to these items and just letting the plane fly you.
