The greatest mistake I've made as an artist is ceasing to invest in myself. I used to be very obsessed with how I presented myself and my work—making sure my blog layouts were impeccable, keeping my deviantArt account up to date with my latest and greatest, making sure everything I did was in tip top shape. Somewhere down the line I lost a lot of confidence in myself and thought it was pointless to invest so much time trying to promote myself when I had nothing worth promoting. I'm sure I felt that way at the time, but I regret thinking that way, nonetheless. I stopped posting to my dA account. I stopped drawing because I was too afraid to start, for fear that it wouldn't be good, or afraid of not knowing what to do. I know now that all this can just be solved by just doing it, but I haven't been.
I'm slowly trying to break out of this rut. It's been too long.
