Deadlimits, no, time-lines, no, wait, time limits. Yes. Life is one great big arbitrary time limit composed of a near infinite number of smaller arbitrary time limits for a huge variety of things we might do or have done.
There is a very limited period of time in which to write this post, but the end could come at any moment. So much depends on a great many factors that are entirely beyond control. We wait.
Wait? No, we write. We're up for the challenge. Why not? It's good practice for living. There may be no tomorrow; or there may be a tomorrow but "there will never be another tonight". Thank you to Canadian "Rock icon" Bryan Adams for the quote. Although the perpetually be-pimpled and pubescent songster is not the first place one would ordinarily turn for wisdom, sometimes how you look at a thing makes worlds of difference. Today we focused on the idea that today is the only one of its kind, never to be repeated, completely original. There may be days that are similar, but... well, you know. Time flows in the one direction for us, as far as we know. So, good or bad, there is hope in this thought. If today is absolutely miserable, it is only one day. If it is fantabulous, it becomes even more incredible when the realization of its unique wonderfantabulousness gets the consideration it deserves. "...Joy to you and me". Goodbye.
