Re: Is two Days a week enough?
I have to agree that you can't judge someone's commitment based only on the number of days of class they attend a week.
Another thing to keep in mind, at least in my opinion, is that some people just learn and progress faster than others. Take two people that both train 3 days a week and their level of aikido will probably not be equal a couple years down the road. It may not be the norm but I know some people who only train 2 days a week that have progressed quicker than people who trained more often.
So I train as much as I can and enjoy it without worrying about how much someone else may be training. Just remember there is always someone in the world who is training more than you are...unless you truly are the person who trains more then everyone else.
