Locktober Mantra for subs. What do you enjoy about denial?

I came across this quote today and sent it to my locked subby for a Locktober mantra.
"It's helpful to remember that discipline is not a burden or some kind of self punishment. To the contrary, discipline is the doorway to personal freedom and joy" - Fleet Maull, PhD

Do you participate in Locktober or are you a fan of chastity? What do you enjoy about denial? What have you learned about yourself in the process of exploring this kink?

Would love to hear from both Dommes and subs!
