Great quotes in this thread!
Here are two more...both from Helen Keller.
“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.”
(I tacked this up in my office after my last break-up (it was a doozy too). Sometime after I met the man who would become my husband.)
The best and most beautiful things in the world cannot be seen or even touched. They must be felt with the heart.”
(I think it's so appropriate that Helen Keller would know this! It touches my heart.)
