No, loving it is not enough.

This is a job, like any other. I'm not going to allow my emotional enjoyment of this job to erode any ability to improve my quality of life or pay. Sorry, as much as management loves to use our enjoyment of our line of work against us. . .I'm not down with playing that game.

I have some very strict professional goals that must be met at various benchmark points. If the goals are not met, I re-evaluate my decision to continue in this profession.
