Had one of those moments today that reminds me why I do this. One of the kids in the group couldn't nail his 400m pace work, got frustrated and wanted to quit halfway through. Sat down with him after, went through his splits from last week, showed him he's actually faster than he thinks. Sometimes they just need to see the progress instead of fixating on what feels hard right now. He came back and smashed the second set. That's the job.
