When I was younger I couldn't understand at all how people could stop doing art. But now that I go to Uni, I just don't have time like I used to, and it's definitely not going to get better once I start working ... so I've been drawing a lot less recently
I just don't always have the energy, because despite being a hobby, art does take a lot of work and concentration. I'd rather sit in front of my computer and browse facebook and tumblr some days.
I also get frustrated with art (everybody does I guess) but somehow that never makes me want to quit drawing alltogether? Like, I get the intense urge to stop posting and sharing art because I feel like I'm horrible, but I never want to quit doing art. I just want to keep it to myself until i'm confident again.
