It sounds like pessimistic realism to me!
Definition of pessimism-
A tendency to see the worst aspect of things or believe that the worst will happen; a lack of hope or confidence in the future.
If you expect the worst, you'll never be disappointed. It does sound very negative.
If you have been trying to have a girl the last with the last 4 children, you must be somewhat of an optimistic person, right? I think the cost of HT changes everything. It is expensive and just not possible for all of us.
As far as hitching ones hopes...the same could be said whether you sway or try HT so I don't see how that helps at all. HT and swaying are BOTH attempts to control something that is not entirely in your control. The difference is the money involved.
I could go outside and get hit by a bus tomorrow but that isn't realism. See the definition above.
