I always see artists asking or hoping for motivation tp come to them. Here a tip, motivation doesn't come to you you bring motivation to you. Set a schedule for times to draw and times to relax. Motivation rarely comes to artists naturally so you have get up and draw yourself. I'm not trying to be mean. Just saying, I have a schedule myself and that's how I get artwork out almost everyday. 99% of the time i don't have any motivation, but once I start to draw on the scheduled days I get into the rhythm of things.

Hope this helped.
