From the very beginning of year of creative habits, it's been my rule to share everyday. There are times when I don't like what I made. Usually I share it anyway. There are times when I don't feel like sharing at all, I'm just in a mood I guess. Usually I share anyway.
Though I've figured out that there are ways to share with out REALLY sharing. These work well when it's been a bad day but they also work for projects that are too personal to share or projects that can't be shared until a later date. So here's some ideas for sharing without really sharing.
Sometimes I photograph my work space. In both of these pictures, my painting is just to the right of the photo, out of the frame.
I'll often take a photo before I begin and maybe I share that one instead of the end result.
I'll take photos during the process. These are usually my favorites photos. (One problem I have with these is I often like these photos better than the end result photos.)
If I'm not happy with a drawing, I might hide it in the shadows of a photo.
Or if something's personal I can put it in the background.
Or on really bad days, I might even show proof of my frustration.
I share each day because it holds me accountable for my creative habit. I don't always have to share my results. I use my photo as proof of my work for the day. Proof can be a messy palette, dirty brushes, leftover scraps, etc. It simply needs to remind me of what I did that day.
