Hmm I've had some made up quotes in the past.
This one I thought of when I was 13 or 14:
"Live to learn,
Learn to Love."
This is said when a family member was wearing something, and I knew I could joke around with them, so when I saw them wearing something I didn't care for I said:
"That looks good...ON YOU!!!"
I think I said that when I was 10 or 11 years old
edit: Try to see the beauty in all things, even if some of these things aren't exactly what most people would call "beautiful".
