My favorite quote is one I made up:
"You can blame others (or things) for your unhappiness or you can be happy."
Another is:
"Wherever you go, no matter what the weather, always bring your own sunshine." ~Anthony J. D'Angelo
Your very own quote is great, Jennifer! It says to me that we choose. Whatever the case - it is our choice - that's really a powerful thought!
And I think it all fits very well with your second quote too.
And it all explains why you come across as such an upbeat person - you're living these - and that's what is really very cool - not just that you like these words - that you put them into action - make them part of who you are!
