You will have your heart broken probably more than once and it's harder every time. You'll break hearts too, so remember how it felt when yours was broken.
You'll blame a new love for things an old one did.
You'll fight with your best friend.
You'll cry because time is passing too fast, and you'll eventually lose someone you love.
So take too many pictures, laugh too much, and love like you've never been hurt because every sixty seconds you spend upset is a minute of happiness you'll never get back.
Don't be afraid that your life will end, be afraid that it will never begin.
