If you talk the talk.

"But (like a boxer) I buffet my body [handle it roughly, discipline it by hardships] and subdue it, for fear that after proclaiming to others the Gospel... I myself should become unfit [not stand the test, be unapproved and rejected]." 1 Corinthians 9:27 AMP

If you are going to talk the talk, then, you too, must walk the walk!
