I want to keep a sketchbook!

I've tried keeping a sketchbook practice over the years, and I always seem to give it up after a short time. This class listed every excuse!
One of my favorite tips from the class is this:
You don't have to finish the page in one sitting.
It seems obvious, yet I tend to feel like I need to finish. Therefore it's easier just never to get started.
I'm showing two pages I made following the class exercises. It took me 3 days to finish each page! I loved the act of slowly making shapes and doodles, not worrying about finishing the page. It helped me relax, my pulse slowed down, and I felt much calmer after 10 minutes of playing around.
I hope to continue this practice!
