I put on some boots, buckle them up, then insert the boots (with my feet in them) into bindings that attach me to some skis. (Yes, I can define what a ski is too.) Then I get on some kind of conveyance (examples include chair lifts and gondolas) that takes me to the top of a hill. I then slide down the hill on my skis, trying to maintain control until I get to the bottom of the slope. I might fall, hopefully not getting injured. If I'm okay, I get up and continue my trip down the mountain. If I get injured the ski patrol comes and gets me and takes me to the hospital. That's skiing.
I get an idea for a story or someone gives me one. Do a little searching on the web, call a few people. Take notes on what I hear. Call some other people or send them emails. Write up the notes on my computer. Organize them into a sequence. Then, I optionally offer it for review to other people to get their opinions and they possibly rewrite it, or I incorporate their feedback and make changes. This is called editing. This process iterates a few times. Then the story is published, usually on a website, and possibly at some later time on paper.
