When the Bible says, “Your Word is a lamp to my feet,” the indication is that God is only going to show us the next step. While it is hard not to think about the past and future, God illuminates for us what we need today (our daily bread). And that’s the only place where we can actually DO anything anyway. – Michael Thompson (http://cslewiswisdom.blogspot.com/2012/01/living-in-present.html)

“The Future is, of all things, the thing least like eternity. It is the most temporal part of time–for the Past is frozen and no longer flows, and the Present is all lit up with eternal rays.” ― C.S. Lewis, The Screwtape Letters

The PRESENT is the only real thing we have.  This is the only time we can really make a difference.  Not in the future for we do not know for sure what lies there.  If you can make it right, make it right NOW, do what you can do now and be present to the people you are with. Worries about the future and regrets about the past will just rob us of the joy we can have in the present.
