I kinda do this too but in a different way? I have a skating friend who’s rly close and we share with each other our progress every time we meet or over text we’ll send videos to each other. We’ll also critique and analyse each other’s elements and what not. We’ll try to help each other out with any problems that we’re encountering in our skating. I guess it’s kinda similar in the sense that there’s this really healthy rivalry between us? When she learns something new or improves on something it motivates me to work even harder and become better, and vice versa. It’s good to be competitive, but I’d say to a healthy extent. Don’t let it consume you, but allow it to motivate you to greater heights :)
