This is perhaps too simplistic. I ran across it on a magnet from a company that specializes in graphic presentations of quotes. Quotable Quotes, I think that company may be called. Anyway, this one has stuck with me, as I consider and try to move forward with my own circumstances. The magnet attributes it to the Cherokee. "Don't let yesterday use up too much of today." It doesn't solve all my problems. But it's a useful reminder; one that is also simple enough to recall at will. It also reads as a useful compromise, to me. Not an admonition to forget yesterday or to "just move on". But a caution not to dwell there, at the expense of the present -- and the future.
