This is kind of trite and rote.
No, you all cannot be a champion. Factor that by one Olympics every 4 years.
I think wanting to win is not important at all.
I think fantasizing that you are winning the Olympic gold while having a blast training your ass off / or on, is the important thing.
Training should be gratifying, always leave some on the track or trail for next time.
Races should be the fun icing on the cake.
I bet you almost everyon's PB felt FUN.
And better than all that stuff, years later... That your teammates and friends are a fraternity or a sorority For Life.
