So incredibly over working at a job that’s unfulfilling

I understand with how bad the job market is right now I am privileged of having a job but DAMN how much it sucks to be working in a job that’s so unmotivating and unfulfilling. I’ve been here a year and a half and I feel like everyday is the same pointless tasks I give myself because my manager is incompetent and won’t give me anything meaningful to do. I’m so close to quitting because I hate this feeling of being so unproductive for 8 hours. Does anyone feel like this as well? I’m 23 and I realize im still young in my career but there’s only so much I can take of being in such a mind numbing job.
