Do you remember how long it took you to learn to write when you were in school, and what that involved? Copying letters over and over and over while your hand and fingers strengthened and got used to the movements?
Drawing/painting/other-forms-of-crafting are no different. You're learning a new skill; give yourself space to grow and be patient while you learn. You might be bad at first but that's fine, you're allowed to be. Keep going. Practice is part of the process. 💪
