Better to stay at a job you love, even if you aren't making the $$ you'd like, and wait it out. Someday you will get the salary boost. Taking a new job, one you might end up hating, isn't worth it. Not even for $100 million a year. Your health and sanity come at a much higher price. All the pay raises in the world can't buy that (trust me, I've been there).

My advice is to stay where you are because you're happy there
