Today, the day you have, is a good day to think of as this day. As in THIS DAY.
For instance, THIS DAY I will do one thing I’ve been putting off until SOME DAY.
By now most of us know that mythical SOME DAY will never come.
Unless we claim THIS DAY to be that SOME DAY.
And if one of the things you’ve been putting off is to go for a walk, today is the perfect day.
THIS DAY. The perfect day, not some day.
