Walk away… It will come eventually. I allow myself and my team to take some time out if the ideas don’t come naturally. No one wants to see a style guide that has been shoehorned into something, that’s just nasty design. I remember my days as a designer sometimes staring at a blank screen and thinking 'come on Stace', but nothing! A creative mind should have the space to breathe, and although we work on multiple projects and deadlines can be tight, we are not doctors and nurses saving the world. So chill out, move on to something else, reengage with the core creative process and allow another path to open up to you. It really sounds cheesy, but it works!
