You don't. Its like the child you wish you had, willing to go through
adoption for the ideal one, and then find out it is not better and
likely worse than the one you have right in front of you. Enjoy the
machine you have, the one you just finished and can tweek and fine tune.
This unless you have to polish a turd. Seriously, its a fun game for
1-2 rounds and then it loses its luster very quicly. Leave the child to
die in the hands of a much more appreciative family, one in another
land, another time, the land of the lost.
