Positive thinking
One of my favorite books of all time is an oldie but goodie called "The Power of Positive Thinking" by Norman Vincent Peale.
I've collected for myself a number of quotations from that book, as well as some other thoughts that make me feel better when I am in need of some extra inspiration.
One day long ago, I typed all of these wise sayings on cue cards using an old-fashioned typewriter. Here they are.
