Here are a few quotes that I think would make fantastic wall decals or plaques to decorate your house with.
"A baby is God's opinion that life should go on." - Carl Sandburg
"Creativity is allowing yourself to make mistakes. Art is knowing which ones to keep." - Scott Adams
"There are flowers everywhere, for those who bother to look." - Henri Matisse
Lastly, I would like to give you a fun word to use. I have heard that if you use a word three times, in context, it will become part of your vocabulary so here is a good one for you.
snarky -adj. snide and sarcastic; usually out of irritation
Kind of random, I know but some words are just funny to me. Plus, being snarky is so much more fun than being sarcastic.
