Staying out of tomorrow when you are in today is very challenging, because it is so tempting to go into tomorrow.
Why is tomorrow... or any further, such an intriguing place?
It may be that the present is not at all where we want to be.
Here's a thought - why not maximize the present?
Every minute can be seen as a real gift to each moment, such as an ocean view, the statuesque trees with the sun streaking through the branches, or a small child laughing uncontrollably. Those moments can be suspended in time long enough to forget about tomorrow… for tomorrow will come soon enough.
