Selfish Reward?

I made a vow to myself when I decided to subject myself to 2 baby deliveries without drugs or other medical interventions, that every year around my kids' birthdays, I would indulge in a massage to commemorate the physical strife I put myself under, in order to avoid medical mishaps that occur with epidurals and drug intervention, to experience the all-natural delivery. Eva's birthday is tomorrow, so my body is preparing for some upcoming relaxation.....

Is this selfish?

The nice part is that because of where I work, I can enjoy a 1-hour massage for $20, and it can be formatted to fit my work-day! I can't wait.
