I remember teachers would tell students off for doodling in class. Now kids are hooked up to the internet where ever they go with smart phones, who needs paper eh! 

Doodling and zen-tangle is also a great form of meditation for those 'mind-conscious' types. I suppose I am trying to say, there is alot of people who don't like to think, not for themselves anyway. They would much perfer to sit infront of a television or drink alcohol. Not that there is anything wrong with watching some of the beautiful creations we have made on digital media platforms but the attention should be spent insearch of personal insight. To seek more about the self, to dive deeper into becoming one with who you are. 

Give doodling a go, you never know what you might find.
