Measuring Dedication

Concepts such as dedication, devotion, and commitment are hard, if not impossible, to quantify. How can I measure the commitment of my sponsors, who give money to this cause year after year after year, when sometimes it seems as if a cure for breast cancer remains distant? Is it possible to calculate the devotion of family members and friends that care for those who suffer from this disease?

If dedication to a cause can be measured by the number t-shirts in one's possession, then I think it's safe to say I'm fairly attached to the idea of a world without breast cancer. I say this somewhat tongue-in-cheek, but take a look at the picture below.
These t-shirts are just some of those I have received as a result of participating in breast cancer walks in the past ten years. Just think about how much more room I'll have in my dresser drawers once a cure for breast cancer is found!
