The Ultimate Code Kata
"Contrary to what you might believe, merely doing your job every day doesn't qualify as real practice. Going to meetings isn't practicing your people skills, and replying to mail isn't practicing your typing. You have to set aside some time once in a while and do focused practice in order to get better at something. ... Separating the practicing from the profession is often referred to as code kata."
