Re: aikido crisis. :(
Although I am not practicing Aikido right now, I am taking an inventory of my experiences of all the MA training I have done, all the experiences, lessons, people, etc, that I have had. I am feeling that I might return to Aikido in the years ahead and one of the ways to keep my "head in the game" is coming here from time to time reading and thinking about Aikido. It looks like you've done similarly. I didn't leave Aikido as a result of a crisis. I came to MA real late compared to many others (38 yrs old). Before that it hardly was a part of my awareness.
90% of my experiences in MA have been good ones. If you are feeling "burned out" you might give it some time, but it might help to keep abreast of the issues that concern the Aikido world and some time you might experience some congruence between Aikido and yourself. This might take a day, a week, a month, many years, whatever.
I don't know, that's just my 2 cents for what it's worth to ya.
Good luck .
