I like the idea of not being afraid of letting your imagination rule you, to feel the freedom of expression, to let creativity be your overwhelming drive rather than other things.
When you're heartbroken, you're at your most creative - you have to channel all your energies into something else to not think about it. Contentment is a creativity killer, but don't worry - I'm very capable of making myself discontented.
Being heartbroken is like having this really horrible freedom. You can be selfish with your thoughts, which can lead to manic creativity, but at the same time you're just really miserable.
