Wow, psychic - I was just about to start a thread on this very topic...
For what it's worth, I voted No..
Don't misunderstand, I think Aikido is probably one of the more worthy ways of making a living - BUT...
I think that one of the great strengths of Aikido is how it can relate to the rest of your life, and likewise how things that happen elsewhere can feed into your Aikido. If you're doing Aikido 24/7 you risk losing this experience, and I wouldn't wish that on anyone...
Peace,
David
