1- Write all your ideas down as soon as these come to mind, no matter how unrealistic these might seem at first. Creativity is not about seeking out logic; it is about ignoring logic and conventional wisdom. A great tool for jotting down your ideas is Evernote. It is available as a desktop application and can also be downloaded as a mobile app.
2- Just change one little thing first because a small change can make a big difference. So for example rather than trying to change the entire structure of some process at work, start by removing a small element or modifying a component of the process and see what the end result is.
3- Don’t over-think or over-plan – focus on getting out a first version of your idea or prototype out there. Creativity is a process sometimes of iterating from an imperfect place to a more effective solution. The act of iteration itself provides guidance on what to change and how best to improve.
4- Search for ideas all around you in places, sights, sounds, color, conversations, the internet, etc. Inspiration can come from any direction and spontaneously.
5- Switch off to switch on – sometimes you just need to switch off and go do something else that has nothing to do with what you have been focusing on. Maybe this is a walk in the park or a good restful nap. When you let go of thinking, the surprising thing is that your subconscious mind starts to work in over-drive and the ideas start to flow again.
