@artofkylin comment reminds me a bit of my own situation.

I've been struggling with a hamstring injury for a long time and therefore can't play my sport, soccer. It doesn't limit me in any other way, but I personally miss not playing soccer a lot, as I've been doing it my whole life.

But I'm already looking forward to the day when the injury is healed, I'm fit again and can get out on the training pitch. Then I'll make every training session and game extra special.
