When one door of happiness closes, another opens

Courage is the power to let go of the familiar.
- Raymond Lindquist

We don't stop playing because we grow old;
we grow old because we stop playing.
- George Bernard Shaw

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 that has been opened for us.
- Helen Keller

Laugh when you can,
apologize when you should,
and let go of what you can't change.
Life's too short to be anything... but happy.
