Patience, practice and have fun with it dude. A little over a year ago I picked up a sketchpad and pencil and just started doodling my dog lying around the house. I’ll throw on my headphones and listen to music while I let my pencil, pen or paint brush lead me see where we ended up. It’s a great escape and absolutely low stakes. What ever comes out isn’t going to be the Mona Lisa, and who cares? You have made something and that is something to be proud of
