A family friend of mine used to play violin in a traveling rock band. He slept in the van and loved every minute of it. Later, when he had a family, he settled down and became a contracted fundraiser for non-profits. One day he came across a particular non-profit that he loved, identified with, and felt excited by. He took a 50% pay cut and settled into a permanent position with that company because "it felt like being back in the van again"
If you're the kind of intrinsically-motivated person who can trick their head into being excited about 12 hours of being immersed in a problem, then you'd be an incredible asset to any company that gets you excited.
If you have an idea of what company, industry, or problem that might be (good news: people usually do), pursue it like hell.
