That is fantastic with your daughter...I hope my future theoretical kids get into martial arts, and wish I had when I was younger.

As for your situation, that sucks that you can't be there, but I'm sure your daughter understands the situation, and it sounds like you do everything except sell a kidney to keep her doing something she loves. You can feel upset at not being there, but don't let that translate into guilt. Sounds like you're doing everything just fine.
