There is more to being a member of a dojo than paying dues. A dojo is a family, and everyone within the dojo has responsibilities and obligations to make the community prosper. Aikido is not a commodity and cannot be bought, given, or received. Aikido is learned and learning takes time and effort.
In the Dojo, a book by David Lowery, is a great introduction to the responsibilities of training in Japanese martial arts. Students should actively participate in the activities of the dojo, from cleaning the dojo to sweeping the mat. Take pride in maintaining a clean practice area. Another important comment is a student's obligation to his (or her) fellow students. We can not train without each other, so make effort to attend class diligently and give others the opportunity to train.
Finally, students should commit to training. Purchase the proper training attire, weapons, and other necessities for class. Share thoughts with fellow students, read books, watch videos, attend class. Commitment is essential to healthy and regular training.
