I encourage my students to try things; to experiment in a low-stakes environment; to screw up. It's our mistakes that teach us everything. Within the world of statistics, I've been an expert for years. The role of expert provided me safety. Yet it also feels dull. Dull, blah, uninteresting. It no longer serves my soul.
So I took some risks. (Besides my upcoming resignation in August.) I experiment with photography and writing, and I often bare myself on this blog. I participate in the online Flickr community, and I bare tender parts of me (the parts that are still unsure about my art; the parts that want critique, but in a gentle voice).
And it's our mistakes that teach us everything.
