One thing I’ve made a habit of in order to motivate my work further is to actively engage with the positive support my work receives: Not only do I encourage and reply to the responses I get, I’ve made a notes list of all of the individual aspects of my art that people have pointed out as positive features and each supportive comment I receive, no matter where I receive it or who it’s from, I save in a photo album to revisit later.
If you enjoy my work, by all means tell me, it means everything to me to hear what you like about it, more so than any money I could make off of it!
