Re: Need some practical advice
I don't see the tattoo being a problem at all; As far as sitting and observing vs. jumping in goes if I am evaluating a dojo I want to consider training in long term I usually observe one class first and then go back and try it on the mat after that. If I am out of town traveling due to work then I try to do some research of dojos in the area ahead of time and just jump on the mat and train.
I work 3:00 PM - 11:00 PM and the only time I can train is Tues/Thur morning from 6:30-7:30 AM so it is almost no sleep on those 2 days before class. Beyond that I normally find myself most comfortable working out between about 10:00 AM and noon on my non class days.
