Re: How effective is aikido in self defense?
Having heart means having the desire and drive to WANT to stay on the mat....that is, NOT making excuses for staying off the mat.
IMO, it is possible to have injuries that keep you off the mat, but the desire can still be in your heart to be on the mat.
Usually if you have heart you find a way to stay on the mat no matter what, but sometimes you just have to stop.
As one of my Ranger Instructors used to say "Ranger, it is important to know the difference between Hooah and Stupid!".
I have lived by this motto for many years!
