Our reading
An editorial interpretation.
The speaker places love of the sport before the desire to please another person. Calling it yours makes participation a matter of personal commitment. The repeated insistence draws a clear boundary between pursuing an activity for oneself and doing it to satisfy someone else's expectations.
