I don't want to play the numbers game, but I am 20+ years of martial arts, but only about 10 of Aikido. I have been around the world with it and got to train under many fantastic people, but sometimes I have dragged myself to training!
I have come home from work and napped to get my energy up, soaked in the bath, downed Red Bull, etc. I have had lots of time the feeling that I just want to stay at home, not train. Now, that is being realistic.
Now, as for Aikido, it is absolutely for me! I train every day, dojo or not - well actually that should be dojo or "dojo"!
