It is never a good idea to bank on what we may have tomorrow.  It makes even less sense to dwell on what we had yesterday.  The only thing that really matters is what we can do right now.  One of the greatest stress inducers in our lives is tomorrow, for it is the unknown.  We worry if "it" will happen, if "it" would happen, what if "it" does happen.  Then we spend time planning for what may never come.  We do that because we think we know the past.  We remember it so well, particularly the pain, the dark days, the unpleasantness we've seen.  We spend our present time and energy protecting the future from the past.  We fail to realize one is over and the other has yet to come.  What we know is now and we have complete control over it -- now.  Nothing can be promised, nor can we own what is no longer.  If we do our best in this moment, we have no time to worry about what may come or has gone.
