How to feel miserable as an artist...Never follow RULES, dictates, or expectations of others when you create! The less lessons the better! Your art is an innate part of your being! We are meant to create! If you simply make your art for your own pleasure without judgment, it will have meaning and purpose for you. Trust me, this is means and end of art!
Do your thing. Do it unapologetically. Don't be discouraged by criticism. You probable already know what they're going to say. Pay no mind to the fear of failure. It's far more valuable than success. Take ownership, take chances, and have fun. And no matter what, don't ever stop doing your thing
