Passion (f)or work

There are some things that I really enjoy doing and I have sometimes thought (briefly) about doing them as a career, but I've always found myself resisting - but not quite being able to put the reason why succinctly into words. Reading the paper today, there was the story of a teacher who recently won $1 million in a poker tournament. When asked if he would give up teaching to play poker professionally, he said he had no plans to. "I love teaching. It's a passion. I love poker, it's a great hobby ... People can lose passion for their jobs and I don't want poker to become work." Nicely put.
