Who said anything about dedicating all their time?
Sure, there are things I would like to do that the skating gets in the way of but that’s what being a parent is about. My wife came from a family that did that as well and they are as far from the STW middle class demographic as you can get yet did their ballet, guiding and whatever else. Similarly my dad was happy enough to drive me around doing SDA’s at uni as it gave us time together.
Like anything else you need your own time to do your own things, I work shifts so I get that, similarly my missus works part time. I have no doubt that as she progresses we will have to manage that time better but there are other things we could do to mitigate if we wanted to.
As for return on our investment, I’d say happiness, a sense of achievement and general development have paid that off many times over. We get a lot out of it too.
