Kids have honestly made me more creative. That's a fact. I was of course creative before kids working as a screenwriter, director and magazine editor...you get the picture. I was born creative, baby. Hear me out though, those kids took my creativity to another level. Throughout history (and I've found throughout my life so far too), creativity arises and thrives within limitations, be it time, budget, tools/access, they exist and are are actually vital in making creativity happen.
Being creative can be hard work. Hard to get the words onto the screen for that next draft, hard to get the confidence to write the book, launch the blog, heck even write that funny tweet. Creatives are riddled with self doubt. Fact.
