There's a little square to circle this with! You sort of allude to it with art, but the way you're thinking of artistic work falls into a wider superset of purposeful work. You might volunteer with
the Make-A-Wish Foundation, a charity organization dedicated to granting a wish for a child in need, or you might be one of the people whose work is depended upon by (
maybe even a great number of) others. I've also seen a shining sense of purpose in their work coming from people in specialized academic fields (like mathematics, geology, and astronomy) and artisan fields not always thought of as art (like cooking, fashion, and teaching).
Also, if you work on some sort of team that would fall apart without especially you, it allots a sense of responsibility as long as that team appreciates that you're the one keeping the lights on. This is exacerbated when they fight for you or seek your input when making big decisions. And if you own the business, it's not terribly uncommon to put down a great number of hours to make your project work, because a business that you created is a labor from your own heart & soul.
There are many contexts in which work is fulfilling, and it can come down to how you engage with that work. You are not your work hours, and you deserve to have some rest. However, it's also good to think about what you might do in with your future, what change you would like to see, and how you're going to get there. If you were to indulge in nothing productive for the rest of your life, would that be a fulfilling existence, or rather, would it be as fulfilling an existence as caring for animals or providing families with food or creating ways & places for other people to seek enjoyment in life?
In my town, there was a local concert venue that shut down a couple years ago, because the owner passed away. He was the single pillar keeping the whole thing afloat. That place was his baby, and he worked himself clear through the bone. It made him happy. He gave others a place where they could share their art, where people could enjoy that art and one another's company. But before he had that, he was doing a lot of thankless labor. In the end, his struggles wound up being preparation for what he would spend his last years on, for something that was meaningful to him.
I say that to illustrate how I square work being unfulfilling with work being purposeful:
You are always working toward something that is meaningful to you.This is often felt acutely by new parents, leaders, and creators alike. You're not likely to find what you seek at your current place of employment. Work can be unfulfilling, thankless, and even dreadful in the moment. However, the lessons & experience you gain from it will often go on to serve you in the future. While I don't strictly mean future employment, it'll help your future self to leverage your past, to build your body of work toward the place where you really want to be. And by that, I don't just mean higher pay; I mean that you'll foster skills, knowledge, and perhaps relationships that'll open the doors to something more fulfilling. You can even tell an employer point-blank that "where you want to be in five years" isn't at that position, but that that position is a step toward your wider goals. Even in those times when it feels like you're not moving, your struggles will always turn into strength.
The only mistake you can make is never using that strength. Your goal is to reach something meaningful, and if you don't have a clear idea of what exactly that might be, your goal is to find out what that is, to look from different perspectives until you can define the shape of your life's goals. Each person defines the metric by which they judge their worth. It doesn't have to be any one thing, and your metric for your own worth will be different from another person's metric for theirs. A failure to you might be a success to others, and vice-versa. I don't believe it's categorically "not good" to find meaning in work that takes up 80 hours of your week. A charity worker might smack me if I tried to tell them that the hours didn't have meaning! No, you want to judge yourself by your own metrics, and others can judge themselves by theirs.
