What gives you a sense of accomplishment? The adjective "accomplished" is so often accompanied with strong nouns like "pianist" or "writer". Yet the feeling of accomplishment can come at unexpected moments.
A friend's eight- year-old daughter was in the backyard on a playhouse contraption with a slide but no ladder. She urged me to climb up the slide, as persuasive as an adult saying, "You can do it." Plopped down on my stomach I hauled myself up to the top of the slide and entered the playhouse. And it felt good to do a thing so out of my usual activities.
The other day I had 2 photos in an exhibit of Miksang photography. http://miksang.com/miksang.html Since I'm neither an artist or a photographer, going to the opening and seeing the photos brought me great pleasure. I don't think I've had anything I've created exhibited since I was in high school or even, middle school.
So life extends its endless possibilities.
