"Cannot do" is an excuse.
I encourage everyone to train as much and as long as they can. Marriage, job, many things can side track or kill training time. I am on extreme side, it is a huge part of my overall life and something many people will not do. Cannot do, is an excuse for we all choose how we spend our time. That is not a judgment of anyone nor does it make me any better than anyone else. It is simply a life choice I have made and that has required many sacrifices and has come with costs, some very painful.
Train as much as you can and as long as you can. Take the skills of the warrior to all aspects of your life and Hapkido will live within you wherever you are in all that you do. This is how I honor the masters who taught me and the sacrifices they made so that we are able to reap the fruits of their labor.
