Here's a few more I love, because I just remembered them.

"When anxiety was great within me, your consolation brought joy to my soul.." - Psalms 94:19
(*I love this one because I can relate to it, when I was going through a rough experience, the comfort of others helped me continue on.)

"We ourselves feel that what we are doing is just a drop in the ocean, but the ocean would be less because of that missing drop." -Mother Teresa
(*When I feel unimportant or that what I do is useless, I think of this quote and it motivates me.)

"And in the end, the love you take is equal to the love you make.." - The Beatles
(*I have one of those wall decals of this because I just love it so, great words to live by definitely.)

"Always.." - Harry Potter and the Deathly Hallows
(*An extremely short quote, and yet it holds so much meaning too. I actually plan on getting this tattoed on my wrist soon.~)
