Doodling-a universal and age old art form. I see cave paintings and petroglyphs as 'doodling'. It's a great way to pass the time and it reduces your cortisol levels (the measure of stress). Which would explain why, when you get to spend a nice chunk of time doing your art, that you feel so euphoric afterwards.
You Tube has a lot of folks that have a 'channel'-it's like their own site on You Tube for their videos. Mine is: pmondoy (which goes to show you that when I first set up my You Tube account, I had no idea what I was doing!). Who would ever randomly search for, 'pmondoy'?
Back to the subject of doodling. There is a channel called, "Miraculous Mosquito"-which is a channel dedicated to doodling and Zentangles. Check it out:
