Shoutout to the Remarkable2 (a new eInk tablet) - it's not for everyone, but as a replacement for a paper notebook it's been great for me. Relevant to OP, it's actually rekindled my drawing. Each week I complete one drawing that takes up about 1/3 of the page while on calls. Because it's eInk it's easier to work with IMO, and I'm noticing improvements. To be clear, I'm not doodling - I'm drawing a scene/object/etc each week. At the start, I decide what I'm going to do and then throughout the week I work on it. Really satisfying and fun. Echoing one of the other suggestions, I've started taking pictures of things that inspire me (a cool scene, a shape, etc), and then will take elements from those pictures to attempt in the weekly drawing.
