And think bigger picture for all of this. Seriously, these are life lessons that are beyond invaluable.
Gymnasts learn to go with the flow, think on their feet, change things as needed at the last minute, trust and work closely with the coach (later in life like a supervisor/manager) ....seriously what amazing amazing skills these kids are learning early.
Say a gymnast later on becomes a teacher - yes there is so much planning and prep work, but in reality so much is reacting to the situation in real time and adapting. Students throw curve balls and you have to adapt.
Or, say later in life a former gymnast's career has him/her preparing for months to research, prepare and deliver a huge important presentation. But, right before it is to be delivered the boss says some slides have to go, or be info has to be changed up - yep, that sure happens in life. A gymnast is so well trained to handle this!! They learned it all at a young age!!
I am the first to admit the sport is so frustrating, whether you are the athlete or the parent - but at dark times I try to step back and remind myself of what this all means over the longer term. (i.e. Good positive stuff)
Hang in there, all yee parents!!
