Being creative is never a bad thing, but sometimes it’s not very productive. You’ve really got to teach yourself to reign it in sometimes.
I’m not surprised to hear that ‘they’ have found a connection between creativity and mental illness. It’s not saying that you have to have a mental illness to be creative, but speaking from experience, you do have to be able to think differently sometimes and unfortunately that is one thing that you don’t have to practice at if you have a mental illness.
Embrace it, that’s what I say. If you’ve got a creative gene, then use it to your advantage. There will always be room on this planet for creative people!
