‘One of These Days’ is a statement of having in the future what I really want today.
It is based on the belief that everything comes to those who wait.
If I work hard enough, long enough, I believe I can afford it, one of these days.
One of these days ‘Lady Luck’ may deliver my dreams.
‘One of Those Days’ is a statement of Murphy’s Law in action.
Murphy’s Law, or Sod’s Law, is the Law of Reversed Action and states that what can go wrong, will go wrong.
When things appear to go wrong for no apparent reason, it is one of those days.
Both statements assume that one is at the mercy of what the day decides to bring.
‘One is the Day’ is a statement of what the day brings is exactly right for me.
I am the Day when I take full responsibility for whatever turns up in my reality.
