I've been suffering from the fear that I can't draw as well as I used to, or as well as I want to anymore. That has kept me from drawing for the past couple of years.
Now I plan to draw and mess up and keep going to teach myself that its okay to make mistakes, and make not perfect art.
The art book I am reading currently is "How to Draw Adorable: Joyful Lessons for Creating Cute Art" by Carlianne Tipsey
