I'm comfortable only when there's a mutual attraction. That's what anyone wants. If I find out she's not attracted to me it brings down my level of attraction to her. If I'm interested and find out she's not I tend to cool off.
But I have found that in the simple act of living with hope and in the daily effort to have a positive impact in the world the days I do have are made all the more meaningful and precious. And for that I am grateful.
