I have a dd who was good at one sport but Covid hit it hard. She was also always good at a second sport, and made the provincial team for the past 3 years so school, province and club training and matches to work around. And there is a separate indoor version that not everyone does but she does and enjoys. (She's just back from an international training camp for it). And she had trials for the national squad but wasn't selected.
Because she wasn't selected for that sport, she got into a 3rd sport this summer. Within the same 7 days, she got a winners medal for the National senior Cup (ladies - not junior) for main sport and came 3rd in national junior champs of the sport she'd just started.
She spends all her time training or at the gym, and eats us out of house and home in chicken/turkey/fish/veg/pasta/rice meals at all hours.
This summer, because she wasn't on the national squad, she was able to get a FT job (except this week) coaching her original sport. And can do that in the US on a J1 when in Uni rather than waitressing (it's in demand on the East Coast for summers).
I am persona non grata since starting secondary so DH does almost all the running of her and her gear (which is so big she can never get lifts with others - they just need a stick and ahi guard where she has a massive bag!) between the various locations and manages who needs to be where and what she can and can't do. He knows which are the good alcohol free beers as he's always driving late in the evening.
Shed is full of all sorts of gear, spares and tools. Her wardrobe is mostly sports gear. There are sports bags for different sports all filled and ready at various points around the house for different things, a drawer of different kinds of specialist shoes for the different sports, and there are lots of showers late at night when she gets in from everything preventing us from going to bed.
