Hugh, of gapingvoid talks about something that a lot of us have probably thought of in Beware of Turning Hobbies into Jobs. (Note, depending on how late you get to this post you might have to use his search box to find the topic.)
"It sounds great, but there is a downside.

What’s true in philanderers, is also true in life."
Beside being a good read, it reminds me of the old saying, "Be careful what you wish for, you might get it."

And he’s happy with his dream job. :o)
