Language Translations

What are some meaningful quotes in the Icelandic Language? Translations please if possible.?

Definition is in the question. I’m looking for for a good saying for a tattoo, and I love the Icelandic language(thanks to Sigur Ros, though they speak Hopelandic in most songs).
Thank you ahead of time everyone!
*Thank you Pere If anyone knows of any other ones, please share! Thanks ahead of time!
