You have that big presentation coming up in a few weeks from now and you are a bit scared. It is easy to put off working on it, forgetting it, until a few days before the event. Wrong strategy.
Start the design process early on even if the brilliant ideas do not flow, then put it away for a while. Your subconscious mind will continue to grind on the presentation and you will be surprised what you can come up with later. If you start this process 48 hours before the event, this creative energy will never be released.
