The learning isn’t in the error, though. The learning is in how you recover from that error and correct it. For instance, when I was young in 4-H, when I made an error with my dog I would immediately overcompensate and start drilling her. Now that I’m older (much older!) I sit back and laugh first, and then figure out where the error occurred, and how to work on fixing it. Let your mistakes be moments to learn, not get frustrated.
Remember! you’re not behind anybody. You’re right where you are, and that’s a good place to be, and a good place to move forward from. Your dog’s all ready to go!
