I recommend you start thinking about how you would teach what you already know. Some people need verbal explanations, how would you explain a technique to them? Some people need to see it, how would you show them? Some people learn best by trial and error, how would you set up a great learning environment for that kind of person?
The most successful dojos have the best teachers. These people not only work hard to perfect their technique, they work hard to learn how to share it with others. If you want to be an Aikido teacher, that's great. Now you have to work twice as hard.
