I agree. I wish I hadn't been so impulsive when first signing up, but life is just a series of lessons I suppose. As an update, I did a lot of research and talked to several local dojos/dojangs and decided to take up krav maga instead of a traditional martial arts form. Classes are 1 hour long and are more of a workout than the TKD classes ever were, and the schedule is much better for an adult who works full-time. Plus other classes are included in the cost, like yoga, kettlebell, etc, which is great to have options. I feel like I actually learn something each time I go, I feel that I'm getting what I pay for, and I love that it's so applicable to real life situations (as a very petite female who lives alone, I would like to be prepared for the worst). I think I've finally found the perfect fit for me. Thanks for all of the support, everyone.
