I pretty much agree with everyone else. But I would like to add what I do to keep from getting bored. I change it up quite often. Fly different planes. Fly differently. Learn to fly low and slow. "This is what I'm doing now." Low and slow inverted passes trying to do tail touches. Learn 3D so that you can do harrier tail drags.
So basically just challenge yourself if you're not afraid of lowing a plane. Check out
www.spadtothebone.com and build a knock around plane for doing fun stuff with such as foam bowling. Foam bowling is stacking a pyramid of foam blocks roughly 2 feet high and knocking em over with the plane. Same can be done with milk jugs. Learn to do it inverted. Try doing low and slow wingtip drags. Etc etc. That kind of stuff is what I do to keep from being bored. How about table top touch and go's. I haven't been able to try this yet but I sure as heck wanna give it a go.
Pretty much I do stuff that I think would be fun. Also I like to do what I call whap and go's with my zagi electric plane. I bring it really low and whap the tips of grass with my plane at full bore. It's hilarious. The list goes on and on. Just be creative with stuff you try. Some people may look down on it but hey, if it's not dangerous then heck..... go for it.
