The tools you use, to help yourself think more creatively are important. However, their job is purely to facilitate your thinking.
Focus on the outcome, not the tools
It’s important not to fall into the trap of believing the tools are what matter most, when it’s the result that counts.
For example, there are countless videos on Mind Mapping, which focus almost exclusively on how pretty the mind map looks, with little if any emphasis placed on the whole point of a mind map, which is to help you think.
Then there are people, who will only think on paper, if that paper happens to be their Moleskine and their favourite pen is to hand. I am a Moleskine user, but many of my best ideas were jotted down on scraps of paper, using someone else’s pen.
Yes, if you happen to think better, when making beautiful mind maps, then make your mind maps look great. If, like me, you carry a Moleskine and wonderful writing pen wherever you go, then use them. However, don’t let your lack of design skills stop you making great progress with your mind map and don’t allow your missing Moleskine to stop you thinking on paper.
Otherwise, the tools simply get in the way of the very process they were designed to assist you with.
