Yesterday was a very good day as I saw Jules Feiffer, got a chance to thank him for his work, and talk with him about his latest book, Cousin Joseph, which is great (hint, hint). It was at an event for Ed Sorel, another great graphic artist.
When I mentioned it to my friends online, one wrote back that I was lucky. I objected, writing that I'd found this event because I look for such opportunities, made note of it, and then went. It was all active decision-making, nothing to do with luck.
But yes, I am lucky in attitude in that I look for such things, notice them when I find them, and then act on that information. Luck paired with determination.
