I have a little journal that I always keep with me, and when I need to, I'll write poems and things. It really helps to clear my head.
I try to remind myself that nothing is permanent.
Things will go wrong or end up differently than you had imagined, and that's OK.
There's music for when you're sad or happy or in love; there's music for every moment in life.
Love is being constantly supportive.
Love is realizing that they are going to make mistakes but knowing you can't hold it against them.
