first of all, never tell yourself it’s impossible. if it’s your dream to be a wonderful artist then you will be, so long as you practice! i’m a twenty-something myself and although i’m constantly viewing and thinking about art, i don’t draw every day. i do, however, always know that the next time i draw, i’ll be better at it. that motivates me to draw again and again so i can eventually reach a place i want to be. all i can really say is to continue striving to be something better than your current self, and learn what motivates you!
