I have to disagree that teaching aikido as a carreer would take awat from your life experience. First, no one does any job 24/7. It would kill you I suspect. People who do only work and have no personal life tend to be on the slightly messed up and unhappy side in my experience. I also think that anybody who is a teacher (of anything) is likely to get a lot of life experience from his/her job, if for no other reason than the constant social interaction and having to adjust to the different needs and personalities of different students.
I voted yes in the poll. Mostly for the reason that I feel most fields of study/practice/art advance best if there are a few skilled people that can truly dedicate themselves to it.
