There are highly gifted spirits who are always infertile simply because, owing to a weakness in temperament, they are too impatient to wait out their pregnancy to term.
Some people wait constructively; they read or knit. I have watched some truly appalling pieces of needlework take form. Others - I am one of them - abandon all thought and purpose to an uneasy vegetative states.
Around every corner is another gift waiting to surprise us, and it will surprise us if we can achieve control over our natural tendencies to make comparisons [to things that are better rather than things that are worse], to take things for granted [rather than imagining how much worse things would be if they weren't there and so feeling grateful], and to feel entitled!
