Honestly it’s not just artists. Most people aren’t working their dream job. I’m doesn’t mean you don’t like your job, but if your dream job paid more, or had more availability, or more security, or whatever it is you’d probably be doing that. Luckily actors typically only have a given job for a few months a year, so they have more flexibility (which is also a risk if you don’t have steady work.)
