Do not always try to be consistent.
Saint Paul, after all, said, "The wisdom of the world is madness in the eyes of God."
To be consistent is always to wear a tie that matches one's socks.
It is to have the same opinions tomorrow as one has today.
And the movement of the planet?
Where is it?
So long as you do no harm to another, change your opinion once in a while.
Contradict yourself without being embarrassed.
This is your right.
It doesn't matter what others think -- because that's what they will think, in any case.
So, relax. Let the universe move about. Discover the joy of surprising yourself.
"God selected the crazy things on the earth so as to embarrass the wise men, " said Saint Paul.
