“When one door of happiness closes, another opens, but often we look so long at the closed door that we do not see the one which has been opened for us.”
– Helen Keller
NOTE: As usual I later looked back for the original source of this quote and verify its attribution to Keller. Turns out she did say it, but some original version of the saying was around before then, and its many sources and variations is muddled if interesting (to me). Regardles, the saying is another of those that I find very True.
