Full day of work

I was programming most of today. Just before vacation I started some changes to this programming I had done. I then stopped due to the holidays. When I returned to work yesterday I dusted it off and realized that I had left it broken, so today I fixed it, improved it and extended it. Now I'm testing it with some new data and realized that the design had several flaws it in. So I made some subtle design changes to accomplish these new requirements. It was fun to not have to toss it all out and start over again. I deftly made the changes while maintaining the existing balance in the design. I'm sure they'll be more changes, but for now I'm happy with it. I kept thinking that it was like sculpting where the form is there, but I had to add a little and subtract a little to adjust the code to get it to work better, that is, making it more general, more powerful and more complete.
