If I could give any advice to any Aikidoist from beginner to expert, I would say master the technical form of Aikido first.  Forget about flashy sexy techniques and just focus on the nuts and bolts of kihon-waza or basic techniques like ikkyo, nikyo, sankyo and yonkyo.  From these four techniques springs all others and if you master them then you can master any of the other techniques in Aikido.  This is not my revelation but Sensei's frequent admonishment to us.  Below is a video that I watch on a regular basis to help remind me of the right form of the movement.  Everyone needs a refresher now and then regardless of how long you have been doing Aikido. https://www.youtube.com/watch?v=VP_jt8WRRsA
