Re: When your family resents Aikido
Maybe just ask them for their support during this time. It could be they've had to take on extra chores and don't have you around as much as they are used to. Remind them of how you supported them for all those years.
Maybe you can give them a reward. For example you could add some new family tradition, Friday night make pizza or do something special with each family member..talk to your family for ideas. Create a new family tradition!
When they want to start a new activity, promise you will support them in it. I think it is a good lesson for them. Sometimes mom becomes such a doormat, they don't appreciate all you do. I think they're starting to, now. I think they'll get used to it after awhile, once they realize you are committed to Aikido.
