Today I took a SQL query - that thankfully someone else wrote - which was taking 6 hours to run, and in about 2 minutes rewrote it so that it finished in 19 seconds. From 6 hours to 19 seconds. The DBA at my office had a huge smile when he saw that.

I love days like today. As soon as I tested the new script, I should have just put on my jacket and went home, because I earned my paycheck right then.

(Sorry if this sounds a little braggy. It's really not. I am just feeling good about that particular moment and had to share. Back to my humble self...)
